dma-debug: use sg_dma_len accessor
debug_dma_map_sg() and debug_dma_unmap_sg() use length in struct
scatterlist while debug_dma_sync_sg_for_cpu() and
debug_dma_sync_sg_for_device() use dma_length. This causes bugs
warnings on some IOMMU implementations since these values are not
same; the length doesn't represent the dma length.
We always need to use sg_dma_len() accessor to get the dma length of a
scatterlist entry.
