Convert function to use folios throughout. This is in preparation for the removal of find_get_pages_range_tag(). This change removes 5 calls to compound_head(). Initially the function was checking if the previous page index is truly the previous page i.e. 1 index behind the current page. To convert to folios and maintain this check we need to make the check folio->index != prev + folio_nr_pages(previous folio) since we don't know how many pages are in a folio. At index i == 0 the check is guaranteed to succeed, so to workaround indexing bounds we can simply ignore the check for that specific index. This makes the initial assignment of prev trivial, so I removed that as well. Also modified a comment in commit_checkpoint for consistency.
