ibmveth: Fix issue with DMA mapping failure
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.
