iommu: Do more input validation in iommu_map_sg() The IOMMU-API works on page boundarys, unlike the DMA-API which can work with sub-page buffers. The sg->offset field does not make sense on the IOMMU level, so force it to be 0. Do some error-path consolidation while at it. Signed-off-by: Joerg Roedel <jroedel@suse.de>
