We need only to explicitly commit in two error cases: -did not queue everything initially scheduled to queue -the last attempt to queue a request failed (see comment of blk_mq_commit_rqs for more details). Both cases can be checked with ret of last request which breaks list walk. Remove unnecessary error count and unnecessary commit triggered by error which is not covered by cases described above.

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.
