[PATCH v15 15/32] v4l: async: Register sub-devices before calling bound callback

[Sakari Ailus]

Register the sub-device before calling the notifier's bound callback.
Doing this the other way around is problematic as the struct v4l2_device
has not assigned for the sub-device yet and may be required by the bound
callback.
