[PATCH v2 2/3] media: vsp1: Don't open-code vb2_fop_release()

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

Use the vb2_fop_release() helper to replace the open-coded version. The
video->lock is assigned to the queue lock, used by vb2_fop_release(), so
the only functional difference is that v4l2_fh_release() is now called
before vsp1_device_put(). This should be harmless.
