rG14fa36d1c1b6: dev/iommu: Include offset in maxaddr check.
rG11fced21ccea: dev/iommu: Include offset in maxaddr check.

Summary

If iommu_gas_match_one has to adjust for a boundary crossing, its check against maxaddr include offset in its calculation, to ensure that the allocated memory does not exceed the max address. However, if there's no boundary crossing adjustment, then maxaddr check disregards the offset. Fix that.
