Subject: [PATCH v2] lib/scatterlist: Remove leftover from sg_page_iter comment

Commit d901b2760dc6 ("lib/scatterlist: Provide a DMA page iterator")
added the sg DMA iterator but a leftover remained in the sg_page_iter
documentation as you cannot get the page dma address (only the page
itself), fix it.
