[sheepdog] [PATCH v3 08/10] sheep: recover objects in the ordered worker thread

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>
The current recovery code are not expected to work in multi threads. However,
cluster_enable_recover() can queue a new recovery work even if there is a
running one. To avoid this problem, this patch uses an ordered work queue for
the recovery work.
