intel-iommu: Fix reference by physical address in intel_iommu_attach_device()
Commit a99c47a2 "intel-iommu: errors with smaller iommu widths" replace the
dmar_domain->pgd with the first entry of page table when iommu's supported
width is smaller than dmar_domain's. But it use physical address directly
for new dmar_domain->pgd...
This result in KVM oops with VT-d on some machines.
