Problem: zyre_get_peer_name is inconsistent and unnecessary

The method name should be "zyre_peer_name" to be consistent with other
similar methods. However that conflicts with an internal zyre_peer
method.

At the same time this method isn't needed since the peer name is sent
along with the ENTER event.

Solution: remove this method.
