Flush or passthrough requests are not accounted as normal IO in completion.
To reflect iostat for slow IO, io_ticks is updated when stat show called
based on inflight numbers.
It may cause inconsistent io_ticks calculation result.
So do not account non-passthrough request when check inflight.
Fixes: 86d7331299 ("block: update io_ticks when io hang")

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.
