f2fs: fix to avoid double unlock
On image that has verity and compression feature, if compressed pages
and non-compressed pages are mixed in one bio, we may double unlock
non-compressed page in below flow:
- f2fs_post_read_work
- f2fs_decompress_work
- f2fs_decompress_bio
- __read_end_io
- unlock_page
- fsverity_enqueue_verify_work
- f2fs_verity_work
- f2fs_verify_bio
- unlock_page
So it should skip handling non-compressed page in f2fs_decompress_work()
if verity is on.
Besides, add missing dec_page_count() in f2fs_verify_bio().
