ctdb-recoverd: Do not fetch the nodemap from the recovery master

The nodemap has already been fetched from the local node and is
actually passed to this function.  Care must be taken to avoid
referencing the "remote" nodemap for the recovery master.  It also
isn't useful to do so, since it would be the same nodemap.
