drm/amdgpu: install ctx entities with cmpxchg
Since we removed the context lock we need to make sure that not two
threads
are trying to install an entity at the same time.

The all listed games are now working with an attached patch.
Also flood messages "WARNING: CPU: 31 PID: 51848 at
drivers/dma-buf/dma-fence-array.c:191
dma_fence_array_create+0x101/0x120" has gone.
That's unfortunately not the end of the story.
This is fixing your problem, but reintroducing the original problem that
we call the syncobj with a lock held which can crash badly as well.
Going to take a closer look on Monday. I hope you can test a few more
patches to help narrow down what's actually going wrong here.
Thanks,
Christian.
Thanks.
