[media] media-device: check before unregister if mdev was registered
Most media functions that unregister, check if the corresponding register function succeed before. So these functions can safely be called even if a registration was never made or the component as already been unregistered. Add the same check to media_device_unregister() function for consistency. This will also allow to split the media_device_register() function in an initialization and registration functions without the need to change the generic cleanup functions and error code paths for all the media drivers.
