wifi: ath12k: Fix invalid RSSI values in station dump

Browse Source 
When processing a "station dump" command, the driver retrieves RSSI
values from the HAL_PHYRX_RSSI_LEGACY TLV received from the monitor
destination ring, and reports them to userspace. Currently, the RSSI
values reported are improper because the hardware has not been
configured to update them properly.

To fix this, enable the HTT_RX_FILTER_TLV_FLAGS_PPDU_START_USER_INFO in
the filter setup to ensure the correct RSSI values are returned in the
HAL_PHYRX_RSSI_LEGACY TLV, resulting in correct RSSI values being
reported to userspace.
