recursor local udp port avoid 4791

When the recursor sends a DNS request and the local port is specified as 4791, if there is RDMA hardware on the machine, when the response with dst as port 4791 reaches the network card driver, it will be directly processed by the hardware as Roce v2 protocol, and the recursor will not get a response to this request.

(cherry picked from commit d0b0158ef76e556c88ab59b2baad8c8d9970543e)
