Emmanuel Grumbach 6522916014 iwlwifi: mei: don't rely on the size from the shared area
If CSME is compromised, it could report a bigger queue size
in the share area and make the host perform an out of bound
access.
Instead of reading the size of the queue from the shared area,
store it in the regular context which is not accessible by CSME.

While at it, fix a small typo in an error print.

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.
