When query_virtqueues() fails, the error log prints the variable err
instead of cmd->err. Since err may still be zero at this point, the
log message can misleadingly report a success value 0 even though the
command actually failed.
Even worse, once err is set to the first failure, subsequent logs
print that same stale value. This makes the error reporting appear
one step behind the actual failing queue index, which is confusing
and misleading.
Fix the log to report cmd->err, which reflects the real failure code
returned by the firmware.

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 reStructuredText 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.
