    ipfilter: Reliably print the interface name
    
    When printing the interface name from the ipstate_t struct the interface
    name in is_ifp may not always be avaiable when reading it from kmem
    (tested on FreeBSD and NetBSD). However the is_ifname (the interface
    name character string) is almost always available -- it is not available
    when the source of the packet is a process running on the firewall
    itself. Rather than print both interface name strings, print only the
    one.
