Memory leak in identify if opening a stream fails.

[Stebalien]

We need to remove the connection from the connection tracker in both of these cases:

go-libp2p/p2p/protocol/identify/id.go

Lines 88 to 103 in fe20b1d

	s, err := c.NewStream()
	if err != nil {
	log.Debugf("error opening initial stream for %s: %s", ID, err)
	log.Event(context.TODO(), "IdentifyOpenFailed", c.RemotePeer())
	c.Close()
	return
	}
	s.SetProtocol(ID)
	// ok give the response to our handler.
	if err := msmux.SelectProtoOrFail(ID, s); err != nil {
	log.Event(context.TODO(), "IdentifyOpenFailed", c.RemotePeer(), logging.Metadata{"error": err})
	s.Reset()
	return
	}

That is, from here:

go-libp2p/p2p/protocol/identify/id.go

Lines 82 to 84 in fe20b1d

	ch := make(chan struct{})
	ids.currid[c] = ch
	ids.currmu.Unlock()
