This lets scsi-* observe the overall s/g list and pass it to the DMA helpers.
size_t can potentially be smaller than dma_addr_t. However, the overall size of a S/G list can actually be bigger than dma_addr_t because (for writes) you could reuse the same buffer multiple times. So there is no difference in practice.
