[PATCH] selftests/net: udpgso_bench_tx: fix dst ip argument

From: wujianguo <redacted>

udpgso_bench_tx call setup_sockaddr() for dest address before
parsing all arguments, if we specify "-p ${dst_port}" after "-D ${dst_ip}",
then ${dst_port} will be ignored, and using default cfg_port 8000.

This will cause test case "multiple GRO socks" failed in udpgro.sh.

Setup sockaddr after after parsing all arguments.

The udpgso_bench_tx equivalent to commit d336509cb9d0 ("selftests/net:
udpgso_bench_rx: fix port argument"). Thanks.
