qcacmn: Update preauth candidate entry to scan table

During SAE roam auth offload, update the beacon/probe response
frame coming from the FW via WMI_ROAM_FRAME_EVENTID into the
scan db.

When the bss info of the preauth candidate is unavailable in
the host/kernel scan entry, supplicant fails to determine the
proper SAE PWE config of the peer and the commit request fails.
