This adds support to help the wireless core with world roaming
by providing hints to when we receive beacons from APs. Devices
can be world roaming when the world regulatory domain is set or
the device has a custom regulatory domain and no country IEs have
been received.
This should should help users more on 5 GHz which doesn't allow beaconing
or active scanning when world roaming.
We call mac80211's beacon hint from ieee80211_mlme_notify_scan_completed(),
which is called at the end of ieee80211_scan_completed(). This guarantees
that we take advantage of devices which do hw-scanning or sw-scanning.
Review with the locking is appreciated, but I think this is OK.
