We used to rely on the returned -ENOSPC of zpool_malloc() to increase reject_compress_poor. But the code wouldn't get to there after commit744e188592("crypto: scomp - fix req->dst buffer overflow") as the new code will goto out immediately after the special compression case happens. So there might be no longer a chance to execute zpool_malloc now. We are incorrectly increasing zswap_reject_compress_fail instead. Thus, we need to fix the counters handling right after compressions return ENOSPC. This patch also centralizes the counters handling for all of compress_poor, compress_fail and alloc_fail.

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.
