btrfs: convert process_page_range() to use filemap_get_folios_contig()
Converted function to use folios throughout. This is in preparation for the removal of find_get_pages_contig(). Now also supports large folios. Since we may receive more than nr_pages pages, nr_pages may underflow. Since nr_pages > 0 is equivalent to index <= end_index, we replaced it with this check instead. Also minor comment renaming for consistency in subpage.
