The qemuxml2argvtest does a bit of 'fixups' to parsed
virDomainDef just before generating the cmd line. For instance,
it sets PCI backend for hostdevs (to VFIO). The reason for this
is that we want to make the test host independent and thus
letting the code chose backend at runtime might render different
results on different machines. But this is not necessary, as
virpcimock (that the test uses) already creates a fake, but
stable environment (where /dev/vfio/vfio and IOMMU groups exist),
thus qemuHostdevHostSupportsPassthroughVFIO() returns true,
regardless of the actual host support.
