Per the nodeJS documentation, a Net socket.remoteAddress value may be undefined if the socket is destroyed, as by a client disconnect. A multiaddr cannot be created for an invalid IP address (such as the undefined remote address of a destroyed socket). Currently the attempt results in a crash that can be triggered remotely. This commit catches the exception in get-multiaddr and returns an undefined value to listener rather than throwing an exception when trying to process defective or destroyed socket data. Listener then terminates processing of the incoming p2p connections that generate this error condition. fixes: https://github.com/libp2p/js-libp2p-tcp/issues/93 fixes: https://github.com/ipfs/js-ipfs/issues/1447
