[libvirt] [PATCH] qemu: Report warning if QoS is set for vhostuser interface

[Michal Privoznik]

https://bugzilla.redhat.com/show_bug.cgi?id=1524230

Because of historical reasons, we are not denying starting a
domain which has QoS set for unsupported type of device. We do
report just a warning instead. And even though we perhaps used to
do so for vhostuser it got lost somewhere. Bring it back.
