selftests/net: udpgso_bench_rx: fix port argument
[ Upstream commit d336509cb9d03970911878bb77f0497f64fda061 ]
The below commit added optional support for passing a bind address.
It configures the sockaddr bind arguments before parsing options and
reconfigures on options -b and -4.
This broke support for passing port (-p) on its own.
Configure sockaddr after parsing all arguments.
