[PATCH v2] media: marvell-ccic: Add missed v4l2_async_notifier_cleanup()

[Chuhong Yuan]

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")
