From: Johannes Berg <johannes.berg@xxxxxxxxx>
When a station that's not associated sends a data frame (e.g. an NDP)
hostapd will respond with a disassoc frame, telling it that it's not
associated. The station might also not be authenticated, in which case
there will not be a station entry for it, and as a result we need to
accept such frames without a station.
