Since commit 422d7df4f090 ("drm/i915: Replace engine->timeline with a
plain list"), we used the default embedded priotree slot for the virtual
engine request queue, which means we can also use the same solitary slot
with the scheduler, so long as we mark the priotree as forever being
that single slot (which we can do by permanently setting no_priotree).
