Update egnn_pytorch_geometric.py

This is due to a naming convention change in torch_geometric v2.3.0, where __attribute__ changed to _attribute. This means attributes like __check_input__ and __user_args__ have been renamed to _check_input and _user_args respectively. More details can be found in this pull request: pyg-team/pytorch_geometric#6999
