for tcp_listener(). fixed potential conflict between implicit
binding and port conflict detection.
Implicit binding automatically allocates an interface address during
connection,but port conflict detection occurs before binding/connecting.
This can cause issues when creating multiple TCP connections in succession.
If the first connection uses a random port via implicit binding, subsequent
connections might reuse the same port under current filtering rules,
leading to connect() failures.
