v4l: async: Protect against double notifier regstrations It can be easy to attempt to register the same notifier twice in mis-handled error cases such as working with -EPROBE_DEFER. This results in odd kernel crashes where the notifier_list becomes corrupted due to adding the same entry twice. Protect against this so that a developer has some sense of the pending failure.
