Enhance check for commands queued to the controller. Add new function pqi_nonempty_inbound_queue_count() that will wait for all I/O queued for submission to controller across all queue groups to drain. Add helper functions to obtain queue command counts for each queue group. These queues should drain quickly as they are already staged to be submitted down to the controller's IB queue. Enhance check for outstanding command completion. Update the count of outstanding commands while waiting. This value was not re-obtained and was potentially causing infinite wait for all completions.

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.
