Before this change, each round's subkey could have leftover bits from the previous round because we didn’t clear key_sets[i].k. This could cause wrong keys during encryption. Now, we set all 8 bytes of the round key to 0 before generating it, which fixes a potential problem and makes subkey generation correct.
