wifi: mac80211: report multicast transmission from lookup_ra_sta()

Browse source

ieee80211_lookup_ra_sta() returns ERR_PTR(-ENOENT) both when the
802.11 frame will be is group addressed and when it's going to
an unknown station.

Keep reporting an ERR_PTR() for group addressed but set to NULL
for individually addressed frames so the callers can use it to
distinguish later. This is already explicitly the case for all
interface types except mesh, and callers already tolerate (but
don't distinguish) both cases.

Also change the ieee80211_lookup_ra_sta() to be static.
