In case of IOCB Queue full or system where memory is low and driver
receives large number of RSCN storm, the stale sp pointer can stay on
gpnid_list resulting in page_fault.
This patch fixes this issue by initializing the sp->elem list head and
removing sp->elem before memory is freed.
Following stack trace is seen
9 [ffff987b37d1bc60] page_fault at ffffffffad516768 [exception RIP: qla24xx_async_gpnid+496]

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
