Laine Stump 846770e5ff util: add missing error log messages when failing to get netlink VFINFO 
This patch fixes the lack of error messages when libvirt fails to find
VFINFO in a returned netlinke response message.

https://bugzilla.redhat.com/show_bug.cgi?id=827519#c10 is an example
of the error message that was previously logged when the
IFLA_VFINFO_LIST object was missing from the netlink response. The
reason for this failure is detailed in

   https://bugzilla.redhat.com/show_bug.cgi?id=889319

Even though that root problem has been fixed, the experience of
finding the root cause shows us how important it is to properly log an
error message in these cases. This patch *seems* to replace the entire
function, but really most of the changes are due to moving code that
was previously inside an if() statement out to the top level of the
function (the original if() was reversed and made to log an error and
return).

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
