ReportFailedAccessCheck() sometimes doesn't throw an exception (it's up
to the embedder). Pretend that OrdinaryDefineOwnProperty() succeeded in
that case. This is consistent with existing behavior of other methods:
- JSObject::DefineOwnPropertyIgnoreAttributes
- JSObject::SetPropertyWithFailedAccessCheck
- Object::SetPropertyWithAccessor
