    sna/dri: Handle TearFree vblanks whilst the pipe is off

    As an extra complication for handling TearFree is that if we attempt to
    requeue a swap whilst the pipe is off, that fails. As we have recursed
    from the pixmap migration path, we have to abort the blit but still send
    the event back to the client so that they unblock.
