[RFC PATCH] drm/sched: Fix preprocessor guard

[Philipp Stanner <phasta@kernel.org>]

When writing the header guard for gpu_scheduler_trace.h, a typo,
apparently, occurred.

Fix the typo and document the scope of the guard.

Fixes: 353da3c520b4 ("drm/amdgpu: add tracepoint for scheduler (v2)")
Signed-off-by: Philipp Stanner <phasta@kernel.org>

I just discovered this. But I have little understanding of what is going
on in this header in the first place, so I kindly ask for comments on
this entire guard line with its logical or ||

The code hasn't been touched since 2015. So it seems it at least didn't
cause bugs.
