mangos.Pipe.GetOption(mangos.OptionTLSConnState) is invalid

[Pekuee]

protocol: req + xrep
transport: tls + tcp

After the certificate is configured, it can send and receive messages normally.
However, does not take effect when a pipe.GetOption(mangos.OptionTLSConnState) is used in a SetPipeEventHook(case mangos.PipeEventAttached) on the server side. The length of tls.ConnectionState.PeerCertificates is 0.

I think I should have found the reason.

https://github.com/nanomsg/mangos/blob/master/transport/tlstcp/tlstcp.go#L187

p.SetOption(mangos.OptionTLSConnState, tc.ConnectionState())

tc.ConnectionState() is invalid before completing the handshake, so it should be set after completing the handshake.
or other better solutions?
