mac80211: remove last_beacon/ave_beacon debugfs files

Browse source 
These file aren't really useful:
 - if per beacon data is required then you need to use
   radiotap or similar anyway, debugfs won't help much
 - average beacon signal is reported in station info in
   nl80211 and can be looked up with iw
