    selftests: net: udpgso_bench_rx/tx: Stop when wrong CLI args are provided
    
    [ Upstream commit db9b47ee9f5f375ab0c5daeb20321c75b4fa657d ]
    
    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.
