[sparsity] Fix for accumulation bug in WeightNormSparsifier (#65293) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/65293 This fixes a bug in the WeightNormSparsifier, where the mask is being multiplied by the newly computed mask. Because the mask elements are binary 0/1, this accumulates the mask over every iteration, eventually collapsing the mask to zero. This bug accidentally bled through from old versions.
