intel-iommu: fix superpage support in pfn_to_dma_pte() If target_level == 0, current code breaks out of the while-loop if SUPERPAGE bit is set. We should also break out if PTE is not present. If we don't do this, KVM calls to iommu_iova_to_phys() will cause pfn_to_dma_pte() to create mapping for 4KiB pages.
