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

commit 704c6c80fb 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.

Fixes: 1380f5754c ("[media] videobuf2: Add missing lock held on vb2_fop_release")
