[PATCH v2 2/4] selftests: net: udpgso_bench_rx/tx: Stop when wrong CLI args are provided

[Andrei Gherzan <andrei.gherzan@canonical.com>]

Leaving unrecognized arguments buried in the output, can easily hide a
CLI/script typo. Avoid this by exiting when wrong arguments are provided to
the udpgso_bench test programs.
