[Re] GPU reset when running the ROCm hsa runtime tests on gfx12 and next-20260701

[Bert Karwatzki <spasswolf@web.de>]

I identified the problem in  
f94bbd648bb4 ("drm/amdgpu: use a single entry point for mes compute reset")
it's reset_queues_mes() being called unconditionally. f94bbd648bb4 can be fixed
like this:

But when I try to fix next-20260701 like this

I still get GPUVM errors (but no GPU reset) and when running

This means there's at least another error in these commits (reverting all these in
next-20260701 fixes the issue)

b789664e3e30 ("drm/amdkfd: Clean up suspend_all and resume_all mes")
