LoRA模块有bug

[fclearner]

https://github.com/alibaba-damo-academy/FunASR/blob/4854d398708594a13e3043daf1a19adfde970ea2/funasr/modules/lora/layers.py#L216

参考loralib的issue: https://github.com/microsoft/LoRA/issues/34 推理的时候没有用到eval()，所以权重没有合并进去

可以用他们的分支代码:https://github.com/microsoft/LoRA/tree/bugfix_MergedLinear

顺带着再贴个苏神的博客：https://kexue.fm/archives/9590
