[libvirt] [PATCH] don't dump core on NULL ifname

[Guido Günther <agx sigxcpu org>]

Hi,
actually I thought I sent this out already, but it seems I didn't:

Don't dump core on NULL ifname when getting interface statistic.
Not all networking types have a target ifname set
(user,client,server,mcast).
Cheers,
