qcacmn: Send the user configured MFP state in RSO command

Browse source 
Currently the user configured MFP state that comes from the
userspace in connect request is not handled or processed.
Instead the RSN caps from assoc IE of connect request is inter-
sected with AP RSN caps and sent to Firmware using RSO command.
This RSN caps is used in FW in selecting a roam candidate, which
was causing the cross AKM (eg:SAE -> PSK) roam fail.
Hence, use the user configured MFP value in sending the RSN caps
to Firmware.
