glusterd: Removing delayed moving of op sm for stop vol/remove brick op.
Earlier we waited for brick disconnect or 5s whichever is smaller, before we move op sm from brick op stage to commit stage. This involves a race where both the above mentioned events can happen 'concurrently' and result in double free.
