Senthil Balasubramanian a59b5a5e68 ath9k: Manipulate and report the correct RSSI 
RSSI reported by the RX descriptor requires little manipulation.
Manipulate and report the correct RSSI to the stack. This will
fix the improper signal levels reported by iwconfig iw dev wlanX
station dump. Also the Link Quality reported seems to be varying
(falls to zero also sometimes) when iperf is run from STA to AP.

Also use the default noise floor for now as the one reported
during the caliberation seems to be wrong.

The Signal and Link Quality before this patch (taken while TX is
in progress from STA to AP)
