    wifi: ath9k: fix LNA selection in ath_ant_try_scan()
    
    [ Upstream commit d6b27eb997ef9a2aa51633b3111bc4a04748e6d3 ]
    
    In 'ath_ant_try_scan()', (most likely) the 2nd LNA's signal
    strength should be used in comparison against RSSI when
    selecting first LNA as the main one. Compile tested only.
