[PATCH v3 3/4] drm/sched: always keep selected ring sched list in ctx entity

[James Zhu <James.Zhu@amd.com>]

Always keep selected ring sched list in ctx entity.
Later entity->sched_list can always be used to track ring which
is used in this ctx in amdgpu_ctx_fini_entity.

v2: fixed typo
v3. Update comments
