Code Review

This pull request correctly fixes a bug in ExaoneMoeModel.get_expert_mapping by passing self as the model argument to the FusedMoE.make_expert_params_mapping class method. The original implementation was missing this required argument, which would result in a TypeError at runtime. The change is accurate and resolves the issue.
