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. Signed-off-by: Johannes Berg <[email protected]>
