drm/amdgpu: check flush fence context instead of same ring v2
Otherwise we can run into the following situation:
1. Process A grabs ID 1 for ring 0.
2. Process B grabs ID 1 for ring 0.
3. Process A grabs ID 1 for ring 1.
4. Process A tries to reuse ID1 for ring 0 but things he doesn't need to flush.
v2: check the context of the flush fence instead of messing with the owner field.
