    Adjust iface_khandler_register() definition to avoid clang 15 warning
    
    With clang 15, the following -Werror warning is produced:
    
        sys/netpfil/ipfw/ip_fw_iface.c:128:24: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        iface_khandler_register()
                               ^
                                void
    
    This is because iface_khandler_register() is declared with a (void)
    argument list, but defined with an empty argument list. Make the
    definition match the declaration.
    
    MFC after:      3 days
    
    (cherry picked from commit edf1e1f78da8c2a19bcee90fe0f72cac2eb18e30)
