blk_mq_all_tag_iter() is added to iterate all requests, so we should
fetch the request from ->static_rqs][] instead of ->rqs[] which is for
holding in-flight request only.
Fix it by adding flag of BT_TAG_ITER_STATIC_RQS.
Fixes: bf0beec060 ("blk-mq: drain I/O when all CPUs in a hctx are offline")

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.
