media: saa7134: Use video_unregister_device for radio_dev

[ Upstream commit 8380a3e9be3ede9a16409bb5fe51ab00158905e2 ]

The radio device doesn't use vb2, thus calling vb2_video_unregister_device()
which results in the following warning being printed on module unload.

WARNING: CPU: 1 PID: 215963 at drivers/media/common/videobuf2/videobuf2-v4l2.c:1236 vb2_video_unregister_device+0xc6/0xe0 [videobuf2_v4l2]
