wifi: ath12k: Fix invalid RSSI values in station dump

Currently, the driver fills RSSI values from the HAL_PHYRX_RSSI_LEGACY
TLV received from the monitor destination ring.  Since driver does not
enable HTT_RX_FILTER_TLV_FLAGS_PPDU_START_USER_INFO during the monitor
destination ring filter setup. As a result, the RSSI values received
from HAL_PHYRX_RSSI_LEGACY are improper because the hardware does not
update them properly. Fix this issue by enabling
HTT_RX_FILTER_TLV_FLAGS_PPDU_START_USER_INFO in the filter setup so
that the correct RSSI values get updated in the station dump.
