    DMA-API.txt: fix description of pci_map_sg/dma_map_sg scatterlists handling

    - pci_map_sg/dma_map_sg are used with a scatter gather list that doesn't
      come from the block layer (e.g.  some network drivers do).

    - how IOMMUs merge adjacent elements of the scatter/gather list is
      independent of how the block layer determines sees elements.
