    drm/i915/execlists: Fix annotation for decoupling virtual request

    As we may signal a request and take the engine->active.lock within the
    signaler, the engine submission paths have to use a nested annotation on
    their requests -- but we guarantee that we can never submit on the same
    engine as the signaling fence.
