    rq == &q->flush_rq was used to determine whether a rq is part of a
    flush sequence, which worked because all requests in a flush sequence
    were sequenced using the single dedicated request.  This is about to
    change, so introduce REQ_FLUSH_SEQ flag to distinguish flush sequence
    requests.
    
    This patch doesn't cause any behavior change.
