Sessionid smb202

[Himantono]

First of all, thank you for the go-smb2. It works good. I cross against a small issue with smb202 server. Sessionid for smb202 is only set by the server if the status is success. If status more proccessing required, sessionid is 0.
I am able to make it working with this changes in session.go. Maybe it is not in the correct place.

func (s *session) recv(rr *requestResponse) (pkt []byte, err error) {
pkt, err = s.conn.recv(rr)
if err != nil {
return nil, err
}
// Added for SMB202, session id is only send if status success
if s.conn.dialect == SMB202 && s.sessionId == 0 && PacketCodec(pkt).Status() == uint32(STATUS_SUCCESS) {
s.sessionId = PacketCodec(pkt).SessionId()
}
if sessionId := PacketCodec(pkt).SessionId(); sessionId != s.sessionId {
return nil, &InvalidResponseError{fmt.Sprintf("expected session id: %v, got %v", s.sessionId, sessionId)}
}
return pkt, err
}

So maybe you can integrate it with your repository or put it in the correct place. Thank you.
