Replace the call to blk_flush_plug_list in blk_mq_submit_bio with a direct call to blk_mq_flush_plug_list. This means we do not flush plug callback from stackable devices, which doesn't really help with the accumulated requests anyway, and it also means the cached requests aren't freed here as they can still be used later on.

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.
