[ Upstream commit 4603a5b4a87ccd6fb90cbfa10195291cfcf6ba34 ]
mccic_register() forgets to cleanup the notifier in its error handler.
mccic_shutdown() also misses calling v4l2_async_notifier_cleanup().
Add the missed calls to fix them.
Fixes: 3eefe36cc00c ("media: marvell-ccic: use async notifier to get the
sensor")
