[libvirt] [PATCH] conf: fix virtType FromString check

[Cole Robinson]

In the domain definition, virtType is virDomainVirtType which is
unsigned, so comparing against -1 doesn't work. Cast to int first

Fixes 8e2982b5767

This regressed in the past as well, when virtType was changed to
virDomainVirtType in 7383b8cc068, fixed by the follow up 5e06a4f063.
It's strange that virDomainVirtType is unsigned but VirtTypeFromString
can return -1... it should probably either work like virArch, or we
should switch virDomainVirtType to int in the DomainDef, but that
requires fixing a few other places too
