Aleksandr Mishin ca6660c956 bnxt_en: Adjust logging of firmware messages in case of released token in __hwrm_send() 
[ Upstream commit a9b9741854 ]

In case of token is released due to token->state == BNXT_HWRM_DEFERRED,
released token (set to NULL) is used in log messages. This issue is
expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But
this error code is returned by recent firmware. So some firmware may not
return it. This may lead to NULL pointer dereference.
Adjust this issue by adding token pointer check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 8fa4219dba ("bnxt_en: add dynamic debug support for HWRM messages")

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.
