Subject: glusterd/snapshot: fixing glusterd quorum during snap operation

During a snapshot operation, glusterd quorum will be checked only
on transaction peers, which are selected in the begin of the
operation, and not on the entire peer list which is susceptible
for change for any peer attach operation.
