media: cedrus: clean up media device on probe failure

Browse Source 
cedrus_probe() initializes the media device before registering the video
device, the media controller, and the media device. If any of those later
steps fails, probe returns without calling media_device_cleanup(), so the
media device internals initialized by media_device_init() are left behind.

Add a media-device cleanup label to the probe unwind path and route video
registration failures through it as well.
