I like this patch so I have applied it, thanks Brian.  I'll
push it to -stable too.

I wonder, since the most accurate return value is tied to the route,
what is expected of this getsockopt() before a socket's identity
(and therefore route) is known?

I suppose returning the default value, which Brian's patch does,
is a reasonable best-effort.
