ibmveth: Fix issue with DMA mapping failure commit b93da27f5234198433345e40b39ff59797bc6f6e upstream. descs[].fields.address is 32bit which truncates any dma mapping errors so dma_mapping_error() fails to catch it. Use a dma_addr_t to do the comparison. With this patch I was able to transfer many gigabytes of data with IOMMU fault injection set at 10% probability.
