Our existing virHashForEach method iterates through all items disregarding the fact, that some of the iterators might have actually failed. Errors are usually dispatched through an error element in opaque data which then causes the original caller of virHashForEach to return -1. In that case, virHashForEach could return as soon as one of the iterators fail. This patch changes the iterator return type and adjusts all of its instances accordingly, so the actual refactor of virHashForEach method can be dealt with later.
