> ATS crashes when no_dns_just_forward is configured without parent proxies

> (and parent routing is enabled)
> and a request comes in that does not have a parent defined for it in
> parent.config ATS will abort with the following backtrace:
> FATAL: HttpTransact.cc:7608: failed assertion `s->parent_result.result ==
> PARENT_FAIL`
