### What this PR does / why we need it? The rotary algorithm in deepseek indexer should be neox-style instead of gptj style. PR #4641 fix this accuracy bug in original pytorch version. But PR #5701 accidentally removed the fixed code line and reverted the implementation back to the problematic version. This PR fixes it. Signed-off-by: rjg-lyh <1318825571@qq.com>
