[libvirt] [PATCH] fix a realloc problem

The attached patch by Dan Berrange fixes it, it's trivial so I commited it, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
