mac80211: Fix IBSS disconnect
commit d4c80d9df6d1e4473b1409e4d220ca3d1612125c upstream.
Currently, when a station leaves an IBSS network, the
corresponding BSS is not dropped from cfg80211 if there are
other active stations in the network. But, the small
window that is present when trying to determine a station's
status based on IEEE80211_IBSS_MERGE_INTERVAL introduces
a race.
Instead of trying to keep the BSS, always remove it when
leaving an IBSS network. There is not much benefit to retain
the BSS entry since it will be added with a subsequent join
operation.
This fixes an issue where a dangling BSS entry causes ath9k
to wait for a beacon indefinitely.
