Atomic<T>#Atomic(T): fix C++ compliance

by not calling `std::atomic<T>::atomic(void)`.

After the latter the instance "does not contain a T object, and its only valid uses are destruction and initialization by std::atomic_init" which we don't call. So the only safe option is `std::atomic<T>::atomic(T)`.
