3.11.10.1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit 78dbfecb95be4635b995af3bd29fa10013409fcd upstream.

The routine that processes received frames was returning the RSSI value for the
signal strength; however, that value is available only for associated APs. As
a result, the strength was the absurd value of 10 dBm. As a result, scans
return incorrect values for the strength, which causes unwanted attempts to roam.
