[pytorch] Make qconv forward() thread safe (#63432) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/63432 There's a race condition in quantized models when multiple threads call forward() due to qnnpack packing the weights the first time the operator is called. This locks the entire apply_impl function. Test Plan: https://github.com/pytorch/pytorch/issues/58055 Ran the script before and after, original crashes went away Reviewed By: kimishpatel Differential Revision: D30229520 fbshipit-source-id: d06cabe24199a80325cd57f24a7fd60624be2cf7
