media: usbtv: Remove useless locks in usbtvvideofree()

Remove locks calls in usbtvvideofree() because are useless and may led to a deadlock as reported here: https://syzkaller.appspot.com/x/bisect.txt?x=166dc872180000 Also remove usbtv_stop() call since it will be called when unregistering the device.
