We already reject null hints (by crashing), and have done for decades.
I don't think there's anything very wrong with the current code, and I
don't really see that the proposed patch is an improvement. If
anything, I'd just add a comment to pg_getaddrinfo_all saying that
unlike bare getaddrinfo, we require a valid hintp.
