Guchun Chen 32f90e6525 drm/amdgpu: prevent memory wipe in suspend/shutdown stage 
On GPUs with RAS enabled, below call trace is observed when
suspending or shutting down device. The cause is we have enabled
memory wipe flag for BOs on such GPUs by default, and such BOs
will go to memory wipe by amdgpu_fill_buffer, however, because
ring is off already, it fails to clean up the memory and throw
this error message. So add a suspend/shutdown check before
wipping memory.

[drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off.

v2: fix coding style issue

Fixes: fc6ea4bee1 ("drm/amdgpu: Wipe all VRAM on free when RAS is enabled")

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.
