[libvirt] [PATCH] don't break on libnuma failures

Another patch hanging in bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=506590 sometimes libnuma can't handle some topologies, but those failures should not completely break libvirt, patch by Dan Berrange. Look sane to me, fixes the main problem for the reporter, so I applied and commited it, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
