In amdgpu_ras_query_error_count() return an error
if the device doesn't support RAS. This prevents
that function from having to always set the values
of the integer pointers (if set), and thus
prevents function side effects--always to have to
set values of integers if integer pointers set,
regardless of whether RAS is supported or
not--with this change this side effect is
mitigated.
Also, if no pointers are set, don't count, since
we've no way of reporting the counts.
Also, give this function a kernel-doc.

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.
