qcacld-3.0: Reserve Beacon Protection Enabled bit in probe req

Currently, irrespective of OP MODE of the driver, the HOST sets
85th bit (Beacon Protection Enabled) in octet 11 of extended
capabilities. As per the 802.11 2020 standard, this field is
reserved for a non-AP STA.

The fix is to make sure 85th bit in octet 11 of extended
capabilities are reserved for a non-AP STA.
