[SYSTEMDS-3729] Fix Federated Response in Roll Function

[min-guk]

I previously wrote the federated roll function to return the result matrix block through a federated response for debugging purposes. Although this does not affect the computation results, it unnecessarily degrades performance, so I will remove it.

Moving forward, I will carefully review the code before committing. I apologize for the inconvenience caused.

Thanks for the patch @min-guk and sorry for missing this debugging relict during the merge of the previous PR.

@mboehm7 Not at all, I should have been more mindful.

I really appreciate your always kind and insightful review!
