[quant][fx] Fix weight_dtype and bias_dtype backend_config checks (#86719) Summary: This PR adds checks for the existence of "weight_dtype" and "bias_dtype" in the node_name_to_dtype dictionary before accessing it, the corner case is hit when we check the compatibility of qconfig and backend_config for weight and bias that appears before activation (e.g. torch.addmm) Test Plan: python test/test_quantization.py -k test_backend_config_check_for_weight_and_bias Reviewers: Subscribers: Tasks: Tags: Pull Request resolved: https://github.com/pytorch/pytorch/pull/86719 Approved by: https://github.com/andrewor14
