Dongliang Mu 85d5345bd8 media: em28xx: fix memory leak in em28xx_init_dev

[ Upstream commit 22be5a10d0 ]

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.
