dbr quant: refactor AutoQuantizationState._get_packed_param_name (#68344)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68344
Makes `AutoQuantizationState._get_packed_param_name` use `seen_op_info`
instead of the current op. This will make future performance improvements
easier.
