    ifconfig: Pacify a sign comparison warning in regdomain_sort.
    
    Both ic_flags values are unsigned (uint32_t), so cast them to a signed
    int to generate a signed result.  Both ic_req values are also
    unsigned, but since they are uint16_t, they are implicitly promited to
    int before the subtraction.
