MEDIUM: connection: only call tcp_connect_probe when nothing was attempted yet It was observed that after a failed send() on EAGAIN, a second connect() would still be attempted in tcp_connect_probe() because there was no way to know that a send() had failed. By checking the WANT_WR status flag, we know if a previous write attempt failed on EAGAIN, so we don't try to connect again if we know this has already failed. With this simple change, the second connect() has disappeared.
