Hans Verkuil 398d768025 media: v4l2-ctrls.c: fix epoll() by calling poll_wait first
The epoll function expects that whenever the poll file op is
called, the poll_wait function is also called. That didn't
always happen in v4l2_ctrl_poll(). Fix this, otherwise epoll()
would timeout when it shouldn't.
