selftests/net: udpgso_bench_rx: fix port argument

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.
