Patrick Daly e29f5d1c4e dma-mapping-fast: Fix iova address leak with non-zero scatterlist offset ...

The underlying arm-smmu hardware only supports mapping addresses
aligned to PAGE_SIZE. Thus the actual mapped region may be larger than
the range returned by iommu_map_sg():

[sg_dma_address(), sg_dma_address() + sg->length)

When unmapping, ensure the same alignment requirements are applied
in order to avoid leaking iova addresses.
