iommu/io-pgtable-arm: Use consistent sizes for page allocation and freeing

At the moment we use alloc_size to allocate memory but then there
is a logical error where we just size in the error and free path,
which might be smaller.
Also we size to do DMA-API operations, which is OK, but confusing.

Instead of this error-prone handling, just set size to alloc_size
and use it everywhere.
