Allen Kay 5341e68f9b intel-iommu: fix superpage support in pfn_to_dma_pte() ...

commit 4399c8bf2b upstream.

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.
