[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](apache/incubator-gluten#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.
