Fixes # (issue)

Hi, we find that below loading method cannot keep the dtype of e_score_correction_bias in safetensors, so raised this PR to fix it. 

Please let me know if this is not the expected change. Thanks.

https://github.com/intel/auto-round/issues/845
```python
from transformers import AutoModelForCausalLM
model_name = "deepseek-ai/DeepSeek-V3.1-Terminus"

model = AutoModelForCausalLM.from_pretrained(
        model_name,torch_dtype="auto"
)

print(model.model.layers[3].mlp.gate.weight) # BF16
print(model.model.layers[3].mlp.gate.e_score_correction_bias) # FP32
```
