foreach_alt_odb: propagate return value from callback
We check the return value of the callback and stop iterating if it is non-zero. However, we do not make the non-zero return value available to the caller, so they have no way of knowing whether the operation succeeded or not (technically they can keep their own error flag in the callback data, but that is unlike our other for_each functions).
