    mac80211: use RX status band instead of current band
    
    Even for single-channel devices it is possible that we
    switch the channel temporarily (e.g. for scanning) but
    while doing so process a received frame that was still
    received on the old channel, so checking the current
    band is racy. Use the band from status instead.
