glusterd: fix op-version bump up flow

Backport of http://review.gluster.org/#/c/11798/

If a cluster is upgraded from 3.5 to latest version, gluster volume set all
cluster.op-version <VERSION> will throw an error message back to the user saying
unlocking failed. This is because of trying to release a volume wise lock in
unlock phase as the lock was taken cluster wide. The problem surfaced because
the op-version is updated in commit phase and unlocking works in the v3
framework where it should have used cluster unlock. Fix is to decide which
lock/unlock is to be followed before invoking lock phase
