iommu/amd: KVM: SVM: Infer IsRun from validity of pCPU destination
Infer whether or not a vCPU should be marked running from the validity of
the pCPU on which it is running. amd_iommu_update_ga() already skips the
IRTE update if the pCPU is invalid, i.e. passing %true for is_run with an
invalid pCPU would be a blatant and egregrious KVM bug.
