Calling opChanged on package suspend / unsuspend

checkAudioOperation returned MODE_IGNORED when a package was suspended,
but any AppOpsWatcher registered for audio operation did not callback
when a package got suspended. This lead to inconsistent state for
services that were watching for app op changes.
