[libvirt] [PATCH] storage_backend_rbd: continue searching when failing in rbd_diff_iterate

From: Chen Hanxiao <chenhanxiao(a)gmail.com&gt; We try to find a snapshot that had no different between the current state of RBD image. If we failed in rbd_diff_iterate, just continue for the next search iteration.
