[sheepdog] [PATCH v2 02/10] sheep: don't try to recover from working directory

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

It is obvious that sheep doesn't have the object in the working
directory.  In this case, recover_object_from_replica() should return
SD_RES_NO_OBJ and try the next node asap.
