[media] drivers/media/video/au0828/au0828-video.c: add missing video_device_release
At the point of the call to video_register_device, both dev->vbi_dev and
dev->vdev have been allocated, and so should be freed on failure. The
error-handling code is moved to the end of the function, to avoid code
duplication.
