glusterd: Handle volinfo->refcnt properly during volume start command
While running the volume start command, the refcnt of the volume is
incremented. At the end of the command, the refcnt should also be
decremented. This is currently not the case.
This patch, makes sure the refcnt is also decremented at the end of the
volume start command.
