Peer probe: Handle probe of friend with multiple hostname
Currently, when a peer is probed with a different hostname already belonging to a cluster, a duplicate entry is created with uuid to set to 0. This leaves the peerinfo in a inconsistent state, and when a detach of this peer is issued, the correct entry gets removed. The fix is to identify a peer with a hostname not matching to the probed hostname and remove the incorrect entry.
