Commit f7b687d6b6 ("staging: r8188eu: remove NumTotalRFPath from struct
hal_data_8188e") removed a for loop around a block of code that is executed
only once when i == 0. However, without the for loop, i will never be set
to 0 before the code block is executed. i remains at 2, which is the final
value after the previous loop. This results in a write past the end of the
powerlevel and MCSBase arrays.
[ 28.480809] Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: rtl8188e_PHY_RF6052SetOFDMTxPower+0x124/0x128 [r8188eu]
[ 28.493752] ---[ end Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: rtl8188e_PHY_RF6052SetOFDMTxPower+0x124/0x128 [r8188eu] ]---
Fix this by replacing i with 0 in the code block that used to be the body of
the loop. While at it, remove the powerlevel array that was just holding a
temporary value.
Tested with Edimax EW-7811Un V2 on an ARM32 embedded system.

Remove the unnecessary _rtw_write_port_cancel() and usb_write_port_cancel()
and embed their code into the caller (i.e., rtw_write_port_cancel()).
_rtw_write_port_cancel() is a mere redefinition of rtw_write_port_cancel()
and it is unneeded. usb_write_port_cancel() was the only functions
assigned to the (*_usb_write_port_cancel) pointer, so we can simply remove
it and make a direct call.
This patch is in preparation for the _io_ops structure removal.
