Pre-5.0 during state transfer an owner could return null to mean "I'm
not sure", so the caller would ignore it unless every target returned
null.
That's no longer necessary, but it wasn't broken so I didn't fix it...
Thinking some more about this, it actually has an performance impact: if the entry does
not exist then there's no point in waiting for all replies, but juts for the first
one.
