usbtv: Remove useless locks in usbtv_video_free() Remove locks calls in
usbtv_video_free() 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. Before ‘c838530d230b’ this issue would only be noticed if you
disconnect while streaming and now it is noticeable even when disconnecting
while not streaming. [hverkuil: fix minor spelling mistake in log message]
