    [CELEBORN-1265] Fix batches read metric for gluten columnar shuffle
    
    ### What changes were proposed in this pull request?
    Fix batches read metric for gluten columnar shuffle
    
    ### Why are the changes needed?
    
![image](https://github.com/apache/incubator-celeborn/assets/107825064/c862e83b-8e3e-4705-a151-41e5b6675d7a)
    
    Due to the fix in 
[Gluten-4025](https://github.com/oap-project/gluten/pull/4051) for the records 
read metric issue, the read metric of CelebornShuffleReader does not need 
additional processing, otherwise the batches read metric will have the issue 
shown in the graph.
    
    ### Does this PR introduce _any_ user-facing change?
    No
    
    ### How was this patch tested?
    CI
    
    Closes #2289 from kerwin-zk/batches-read.
