What does this PR do?

  1. Fixes RuntimeError: unscale_() has already been called on this optimizer since the last update(). #24050
  2. Context: We weren't handling properly the auto_find_batch_size=True case. Here, we need to free all of the stored model references in the Accelerator each time as mentioned in the https://github.com/huggingface/accelerate/blob/main/examples/by_feature/automatic_gradient_accumulation.py
  3. This PR does that.
