Vishal Kulkarni db1c0da0a0 cxgb4: Fix kernel panic while accessing sge_info
[ Upstream commit 479a0d1376f6d97c60871442911f1394d4446a25 ]

The sge_info debugfs collects offload queue info even when offload
capability is disabled and leads to panic.

Fix this crash by skipping the offload queue access in sge_qinfo when
offload capability is disabled

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.
