James Smart e0ddd176a3 scsi: lpfc: Fix release of hwq to clear the eq relationship
[ Upstream commit 821bc882accaaaf1bbecf5c0ecef659443e3e8cb ]

When performing reset testing, the eq's list for related hwqs was getting
corrupted.  In cases where there is not a 1:1 eq to hwq, the eq is
shared. The eq maintains a list of hwqs utilizing it in case of cpu
offlining and polling. During the reset, the hwqs are being torn down so
they can be recreated. The recreation was getting confused by seeing a
non-null eq assignment on the eq and the eq list became corrupt.

Correct by clearing the hdwq eq assignment when the hwq is cleaned up.

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.
