locks: Ensure local lock removal after a failed refresh (#12979)

In the event when a lock is not refreshed in the cluster, this latter
will be automatically removed in the subsequent cleanup of non 
refreshed locks routine, but it forgot to clean the local server, 
hence having the same weird stale locks present.

This commit will remove the lock locally also in remote nodes, if
removing a lock from a remote node will fail, it will be anyway 
removed later in the locks cleanup routine.
