Nvme protocol define local retry and path error. Nvme retry mechanism should not care blk status, just need use nvme status. The mechanism is: non path related error will be retry local, path related error will be treated by multipath. For nvme mulitpah or other multipath(like dm-multipath), retry mechanism is same.
