[sheepdog] [PATCH v2 06/14] corosync: show better error messages

[MORITA Kazutaka]

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

If cpg_initialize() returns CS_ERR_SECURITY, the error reason is sheep
doesn't have a privilege to use corosync because of corosync
configuration.  In this case, printing "Permission denied" is better.

In the other cases, corosync is actually running and there is another
error reason.  This removes "is corosync running?" from the error
message in the default cases.
