So far the assumption was that each dma scatter list entry contains only a single page. This might not hold in the future, when we'll introduce compact scatter lists, so prepare for this everywhere in the i915 code where we walk such a list. We'll fix the place _creating_ these lists separately in the next patch to help the reviewing/bisectability.
