Summary: There's a discrepancy in the SDPA impl when computing w/wo paddings as invalid cache, even it's masked out. For verification purposes, we need to test eager model without paddings to match results with QAT model. The change is to handle cases where cache_len == 0, preventing crashes in cache updates.
