Add an additional arg to __folio_start_writeback() that takes in the

Usually we pass something like page+nr_pages so we know the actual range. I
assume here this is not required, because we only care about using the
#pages for accounting purposes, right?
I think all the "nr_pages" here are actually the number of dirty pages
in the folio, right? Or so I gather since later patches have iomap
walking bitmaps to find all the set/clear bits. Perhaps that parameter
ought to be called nr_dirty(_pages)?
That would make perfect sense to me :)
