glusterd: fail volume delete if one of the node is down
Deleting a volume on a cluster where one of the node in the cluster is down is
buggy since once that node comes back the resync of the same volume will happen.
Till we bring in the soft delete feature tracked in
http://review.gluster.org/12963 this is a safe guard to block the volume
deletion.
