quant: make each line of fx/quantize.py <=80 chars (#48357)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/48357
Cleans up the long lines in `torch/quantization/fx/quantize.py`
to fit the 80 character limit, so it's easier to read and looks
better on FB's tools.
In the future we can consider adding a linter for this.
