media: exynos4-is: Fix recursive locking in isp_video_release()

commit 704c6c80fb471d1bb0ef0d61a94617d1d55743cd upstream.

>From isp_video_release(), &isp->video_lock is held and subsequent
vb2_fop_release() tries to lock vdev->lock which is same with the
previous one. Replace vb2_fop_release() with _vb2_fop_release() to
fix the recursive locking.
