When the device joins an AP, beacon are forwarded to the host. Once has
retrieved all necessary parameters, we can start to filter the beacon
(and only beacon with changed/new data will be forwarded).

Currently, the driver detect beacons in data Rx process. It is far more
easier to just wait for the BSS_CHANGED_BEACON_INFO event.
