James Smart 731eedcb31 scsi: lpfc: Fix deadlock due to nested hbalock call
If an adapter fails, causing a board reset, the board reset routine
lpfc_hba_down_s4() takes the hbalock out then calls
lpfc_nvmet_ctxbuf_post() who then tries to take out the same lock.  As the
context lists are now protected under the buf_list_locks, there is no need
for the hbalock to be held by the board reset routine.

Fix by no longer taking the hbalock in the board reset routine.

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.
