Chao Yu 74878565fb 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().
