The server binds the queues for zero-copy after listen(). If the client does a connect() during this time it can fail with EHOSTUNREACH on a cold system. This was encountered with the mlx5 driver where binding the .ndo_queue_start() is a slow operation during which no packets can be exchanged. This change moves listen() after queue binding, when the test server is fully operational.
