iommu/vt-d: Return the correct dma mask when we are bypassing the IOMMU
We must return a mask covering the full physical RAM when bypassing the
IOMMU mapping. Also, in iommu_need_mapping, we need to check using
dma_direct_get_required_mask to ensure that the device's dma_mask can
cover physical RAM before deciding to bypass IOMMU mapping.
Based on an earlier patch from Christoph Hellwig.
