[ Upstream commit b4fd63f42647110c963d4bfcd526ac48f5a5faff ]
This reverts commit 7e70aa789d4a0c89dbfbd2c8a974a4df717475ec.
Now that we have the patches ("blk-mq: In blk_mq_dispatch_rq_list()
"no budget" is a reason to kick") and ("blk-mq: Rerun dispatching in
the case of budget contention") we should no longer need the fix in
the SCSI code. Revert it, resolving conflicts with other patches that
have touched this code.
With this revert (and the two new patches) I can run the script that
was in commit 7e70aa789d4a ("scsi: core: run queue if SCSI device
queue isn't ready and queue is idle") in a loop with no failure. If I
do this revert without the two new patches I can easily get a failure.

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.
