fx quant: fix prepacking for F.conv1d (#55311)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/55311
Before this PR, `F.conv1d` was matched by FX graph mode quant patterns
but the prepacking was happening inline. There was also a bug with
argument type mismatch.
This PR fixes both issues and adds a test. Thanks jerryzh168 for the
code tip.
Test Plan:
```
python test/test_quantization.py TestQuantizeFx.test_functional_not_reference
```
