[sheepdog] [PATCH 2/2] sheep/group: allow sending SD_OP_GET_EPOCH to delayed nodes

[MORITA Kazutaka]

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

We cannot check whether the node is a delayed one or not in
epoch_log_read_remote() because we cannot access delayed node list in
the worker thread.  It is not a problem to send SD_OP_GET_EPOCH to
delayed nodes, so let's simply allow it.
