s390/atomic_ops: Let __atomic_add_const() variants always return void

Browse Source 
Depending on MARCH_HAS_Z196_FEATURES __atomic_add_const() returns void or
the previous value before the atomic variant. Make sure that for both cases
void is returned so potential incorrect usage results in both cases in a
compile error.
