drm/amdgpu: fix fairness in enforce isolation handling
Make sure KFD gets a turn when serializing access to
the GC IP. Currently non-KFD jobs can starve KFD if they
submit often enough. This patch prevents that by stalling
non-KFD if its time period has elapsed.
v2: fix units
v3: check enablement properly
