      Description

      A client panics if a request succeeded but the following processing failed.
      The flow is below.

      mdc_enqueue_base
       ldlm_cli_enqueue 
        ptlrpc_queue_wait      // succeeded, that is, req->rq_transno != 0
        ldlm_cli_enqueue_fini  // failed, that is, rc != 0
         ldlm_lock_change_resource // error ex. ENOMEM
       mdc_clear_replay_flag
        LBUG // <-
      

      There are serveral ways that ldlm_cli_enqueue() may fail even if ldlm_cli_enqueue() succeeded. LBUG should be removed.
