[inductor] test_fft_real_inputs fails with dynamic shapes
Labels: good first issue, triaged, oncall: pt2, module: dynamic shapes, module: inductor

### 🐛 Describe the bug

```python
python test/inductor/test_torchinductor_dynamic_shapes.py -k fft
python test/inductor/test_torchinductor_codegen_dynamic_shapes.py -k fft
```

(you will need to un-xfail the tests in `test_torchinductor_(codegen)?_dynamic_shapes.py` files)

Fails with this error:
