[PATCH 1/1] STA: Reduce the time taken for initial association when FW ROAM is enabled

[Jithu Jance]

If Driver advertises the FW_ROAM, the supplicant doesn't pass down
the bssid and freq in the connect req(even though supplicant has these
info from its scan). This forces the firmware to do a full scan again
finding out the AP to JOIN. Instead FW can already make use of the scan
done by the supplicant for the first association. In case if some fw
doesn't require it, it can just ignore the bssid.

IMHO, passing down the bssid and freq adds more flexibility and
will help to improve the connection timings. Please see whether
the patch is fine.
