station/wsc: remove beacon loss handling

Browse Source 
Modern kernels ~5.4+ have changed the way lost beacons are
reported and effectively make the lost beacon event useless
because it is immediately followed by a disconnect event. This
does not allow IWD enough time to do much of anything before
the disconnect comes in and we are forced to fully re-connect
to a different AP.
