[libvirt] [PATCH libvirt] interface: don't error out if a bond has no interfaces

[Lubomir Rintel]

It's not a problem at all and causes virt-manager to break down.

Note: netcf 0.2.8 generates invalid XML for a bond with no interfaces anyway,
so this error is in fact not reached as we fail earlier. Fix submitted upstream.
