Fail to generate forward.mlir for DeepLearning/Layers/FFN

[ShizhenWang2027]

Describe the bug
I tried the benchmark of DeepLearning/Layers/FFN but encountered a list index out of range problem as following:

Traceback (most recent call last):
File "/data/data5/szwang/workspace/NPUv2/buddy-benchmark/buddy-benchmark/benchmarks/DeepLearning/Layers/FFN/buddy_ffn_import.py", line 85, in

ninja: build stopped: subcommand failed.

To Reproduce
Just follow the instructions in benchmarks/DeepLearning/README.md.
