rbd: don't test rbd_dev->opts in rbd_dev_image_release()
rbd_dev->opts is used to distinguish between the image that is being
mapped and a parent. However, because we no longer establish watch for
read-only mappings, this test is imprecise and results in unnecessary
rbd_unregister_watch() calls.
Make it consistent with need_watch in rbd_dev_image_probe().
