[Sheepdog] [PATCH] sheep: if fail to read copy from replication, retry it

[yaohaiting.wujue at gmail.com]

From: HaiTing Yao <wujue.yht at taobao.com>

1, Retry all of the replication, so will not breaking from the loop

2, Assign the actual returning value, because the EIO maybe lead to node
leaving the cluster.
