V4L/DVB (7122): saa7134-empress: Remove back lock
videobuf functions at close() method already locks videobuf. It makes no sense to keep the locking at empress close() method. There is also a lock at open() method. I'm not sure if it is safe to remove the locking there. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
