[libvirt] [PATCH] [RFC] net: don't segfault on Martin's setup

No, don't worry, this is not a real commit message, this is more like an RFC about how to fix it. I'm not sure about this part of libvirt codebase, so I'm rather asking for help. Apparently, I have a network with netdef->forward.pfs == NULL, I suspect this is a network I have, that doesn't have any <forward/> element. With the following fix, everything works as expected, but I'm almost certain this is not enough.
