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.
