media: v4l: async: Properly re-initialise notifier entry in unregister

Browse source

commit 9537a8425a upstream.

The notifier_entry of a notifier is not re-initialised after unregistering
the notifier. This leads to dangling pointers being left there so use
list_del_init() to return the notifier_entry an empty list.

Fixes: b8ec754ae4 ("media: v4l: async: Set v4l2_device and subdev in async notifier init")
