mac80211: fix driver RSSI event calculations
commit 8ec6d97871f37e4743678ea4a455bd59580aa0f4 upstream. The ifmgd->ave_beacon_signal value cannot be taken as is for comparisons, it must be divided by since it's represented like that for better accuracy of the EWMA calculations. This would lead to invalid driver RSSI events. Fix the used value.
