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().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
