James Smart 51a2104cc4 scsi: lpfc: Fix hdwq sgl locks and irq handling 
commit a4c21acca2 upstream.

Many of the sgl-per-hdwq paths are locking with spin_lock_irq() and
spin_unlock_irq() and may unwittingly raising irq when it shouldn't. Hard
deadlocks were seen around lpfc_scsi_prep_cmnd().

Fix by converting the locks to irqsave/irqrestore.

Fixes: d79c9e9d4b ("scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware.")

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.
