    conf: report an error if nic needs filtering by no driver is present
    
    If a <interface> includes a filter name but the nwfilter driver is not
    present we silently do nothing. This is very bad, because an application
    that thinks it is protected by malicious guest traffic will in fact be
    vulnerable. Reporting an error gives the administrator the ability to
    know there is a problem and fix it.
