block: Add some exports for bcachefs

- bio_set_pages_dirty(), bio_check_pages_dirty() - dio path - blk_status_to_str() - error messages - bio_add_folio() - this should definitely be exported for everyone, it's the modern version of bio_add_page() Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Cc: linux-block@vger.kernel.org Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> Link: https://lore.kernel.org/r/20230813182636.2966159-2-kent.overstreet@linux.dev Signed-off-by: Jens Axboe <axboe@kernel.dk>
