glusterd: Adding transaction checks for cluster unlock.

While a gluster command holding lock is in execution,
any other gluster command which tries to run will fail to
acquire the lock. As a result command#2 will follow the
cleanup code flow, which also includes unlocking the held
locks. As both the commands are run from the same node,
command#2 will end up releasing the locks held by command#1
even before command#1 reaches completion.

Now we call the unlock routine in the code path, of the cluster
has been locked during the same transaction.
