    sna/gen6: Restore stall dropped when not flushing instead

        sna/gen6: Tweak flush around CC state changes

    Replaced the pipeline stall with a flush - but only when the target was
    dirty. The missing stall however seems to be required as well.

    v2: Actually emit the stall for all CC state changes [Ilia Mirkin]
