cfg80211: call disconnect_wk when AP stops

[ Upstream commit e005bd7ddea06784c1eb91ac5bb6b171a94f3b05 ]

Since we now prevent regulatory restore during STA disconnect
if concurrent AP interfaces are active, we need to reschedule
this check when the AP state changes. This fixes never doing
a restore when an AP is the last interface to stop. Or to put
it another way: we need to re-check after anything we check
here changes.
