[ 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.
