cfg80211: call disconnect_wk when AP stops

commit e005bd7ddea06784c1eb91ac5bb6b171a94f3b05 upstream.

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.
