Sara Sharon 0916224eaa iwlwifi: pcie: fix erroneous print
When removing the driver, the following flow can happen:
1. host command is in progress, for example at index 68.
2. RX interrupt is received with the response.
3. Before it is processed, the remove flow kicks in, and
   calls iwl_pcie_txq_unmap. The function cleans all DMA,
   and promotes the read pointer to 69.
4. RX thread proceeds with the processing, and is calling
   iwl_pcie_cmdq_reclaim, which will print this error:
   iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0),
   index 4 is out of range [0-256] 69 69.

Detect this situation, and avoid the print. Change it to
warning while at it, to make such issues more noticeable
in the future.

README

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.
