Will cause below warning then reboot when exercising the decoder with
fluster on mt8192-asurada-spherion.
This deinit function is called on the v4l2 release callback, even though
the work might not have been initialized as that only happens if/when the
codec specific 'decode' callback is called (as a result of device_run m2m
callback).
