ath.git fixes for 5.11. Major changes:
ath11k
* add null check for skb allocation
* fix crash found during connect/disconnect stress testing
* fix for HT disabled case
* brown paperbag fixes for my bugs in suspend code
* fix an unnecessary qmi allocation during firmware bootup
* disable ASPM during firmware bootup to avoid issues
Not all firmware versions support allocating DMA memory in smaller blocks so
first try to allocate big block of DMA memory for QMI. If the allocation fails,
let firmware request multiple blocks of DMA memory with smaller size.
This also fixes an unnecessary error message seen during ath11k probe on
QCA6390:
ath11k_pci 0000:06:00.0: Respond mem req failed, result: 1, err: 0

The "if (!ret)" condition is inverted and it should be "if (ret)". It means
that we return success when we had intended to return an error code. This also
caused a spurious warning even when the suspend was successful:

For QCA6390, bss peer must be created before vdev is to start. This
change is to start vdev if a bss peer is created. Otherwise, ath11k
delays to start vdev.
This fixes an issue in a case where HT/VHT/HE settings change between
authentication and association, e.g., due to the user space request
to disable HT.

ath.git patches for v5.11. Major changes:
ath11k
* suspend support for QCA6390 PCI devices
* support TXOP duration based RTS threshold
* mesh: add support for 256 bitmap in blockack frames in 11ax
Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.
At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.
During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state. During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

Firmware will check all the pipes before entering WoW mode during suspend. If
ATH11K_HTC_FLAG_NEED_CREDIT_UPDATE is set, firmware treats this pipe needed to
return credit even though it's actually not required. If any pipe needs to
return credit, the suspend_complete message doesn't send to host but is
dropped. So host gets time out and WoW suspend failed.

Just when resume from WoW, the write to select_window doesn't take
effect immediately, so read the register again to ensure the write
operation is finished.
Another change is to reset select_window to ZERO because this
register isn't restored after WoW, so the content of this register
becomes ZERO too.

Currently 6G specific tlvs have duplicate entries which is causing
scan failures. Fix this by removing the duplicate entries of the same
tlv. This also fixes out-of-bound memory writes caused due to
adding tlvs when num_hint_bssid and num_hint_s_ssid are ZEROs.

There was no way to detect if the firmware crashed so add a warning. At the
moment the firmware is not restarted or anything like that, so when this
happens ath11k modules need to be reloaded.

When it has more than one restart_work queued meanwhile, the 2nd
restart_work is very easy to break the 1st restart work and lead
recovery fail.
Add a flag to allow only one restart work running untill
device successfully recovered.
It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this
flag again, because it is clear in ath10k_core_start. The function
ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do
many things and drv_start(call to ath10k_core_start) is 1st thing,
when drv_start complete, it does not mean restart complete. So it
add new flag and clear it in ath10k_reconfig_complete, because it
is the last thing called from drv_reconfig_complete of function
ieee80211_reconfig, after it, the restart process finished.
