This is a small cleanup coming from the pKVM SMMUv3 support [1].
However, they are not pKVM specific and useful in general.

The first patch is to fix a theoretical issues with alloc/free size.
The second patch is the main one to convert the code to iommu-pages.
The third patch is a cleanup to use address conversion consistently.
