Yihang Li 9e1986cd8a scsi: hisi_sas: Check before using pointer variables
[ Upstream commit 8dd10296be8562a45c6c6794dd492a2b7dccede8 ]

In commit 4b329abc91 ("scsi: hisi_sas: Move slot variable definition in
hisi_sas_abort_task()"), we move the variables slot to the function head.
However, the variable slot may be NULL, we should check it in each branch.

Fixes: 4b329abc91 ("scsi: hisi_sas: Move slot variable definition in hisi_sas_abort_task()")

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.
