A "connected network" is a network that points to a valid virConnectPtr.
 But based on the way we do reference counting, this should ALWAYS be
the case for a valid network.  This is the same intentional change as
was made for domains in commit 6e130dd.  I'll tweak the commit message
to make the justification stronger.

Even though it is now after freeze, this was reviewed before freeze and
I think it's better to have the whole series in the release rather than
half-and-half.  So I'll keep plowing through your review comments, and
in particular, I have now pushed this patch.
