drm/i915: Add null state batch to active list
for proper refcounting to take place as we use
i915_add_request() for it.
i915_add_request() also takes the context for the request
from ring->last_context so move the null state batch
submission after the ring context has been set.
v2: we need to check for correct ring now (Ville Syrjälä)
v3: no need to expose i915_gem_move_object_to_active (Chris Wilson)
v4: cargoculted vma/active/inactive error handling removed (Chris Wilson)
