    tools/kdd: alternative way of muting spurious gcc warning
    
    Older gcc does not support #pragma GCC diagnostics, so use alternative
    approach - change variable type to uint32_t (this code handle 32-bit
    requests only anyway), which apparently also avoid gcc complaining about
    this (otherwise correct) code.
    
    Fixes 437e00fea04becc91c1b6bc1c0baa636b067a5cc "tools/kdd: mute spurious
    gcc warning"
