media: em28xx: fix memory leak in em28xx_init_dev
In the em28xx_init_rev, if em28xx_audio_setup fails, this function fails
to deallocate the media_dev allocated in the em28xx_media_device_init.
Fix this by adding em28xx_unregister_media_device to free media_dev.
BTW, this patch is tested in my local syzkaller instance, and it can
prevent the memory leak from occurring again.
