    [fix][txn]: fix pending ack is recovering throw CursorAlreadyClosedxception 
(#14781)
    
    ### Motivation
    When Transaction PendingAck recover fail throw 
CursorAlreadyClosedException, we should stop the recover op. the cursor was 
been closed, the pendingAck was been closed, so we should stop the recover op, 
in order to release thread resources
    
    ```
