    Adjust iface_khandler_deregister() definition to avoid clang 15 warning
    
    With clang 15, the following -Werror warning is produced:
    
        sys/netpfil/ipfw/ip_fw_iface.c:159:26: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        iface_khandler_deregister()
                                 ^
                                  void
    
    This is because iface_khandler_deregister() is declared with a (void)
    argument list, but defined with an empty argument list. Make the
    definition match the declaration.

    (cherry picked from commit 4100dc46c78cef408369c0fc8dcfd1f87783a1ca)
