    drm/i915/execlists: Lock the request while validating it during promotion

    Since the request is already on the HW as we perform its validation, it
    and even its subsequent barrier may be concurrently retired before we
    process the assertions. If it is retired already and so off the HW, our
    assertions become void and we need to ignore them.
