MLK-11508-2 v4l2: Add v4l2_async_notifier_unregister recursively call

If anyone calls v4l2_async_notifier_unregister() recursively from
device_release_driver(), code will deadlock at list_lock, so unlock
list_lock when device_release_driver() called.

(cherry picked from commit f0b54df4d1b58f8f6608e1b08a80a5acb8cc12ea)
