Networking: Fix a major TCP bug introduced with commit e71c09ce9777ff732cb60bd07fb43d85522f79d6. Some connection logic was reorder -- setting the socket got moved BEFORE the point where the check was made if the socket was already connected. The resulting behavior was odd: Telnet would connect, but then when you exit and reconnect, it would fail to connect. But then if try again, it would connect okay. So the symptom was connect-fail-connect-fail-...
