    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)
