Fix bug #9016 - Connection to outbound trusted domain goes offline.

Fix bug #9016 - Connection to outbound trusted domain goes offline.

By the time we've gotten to init_dc_connection_network() we shouldn't
be second guessing the caller by calling winbindd_can_contact_domain().

If for some reason we do need to restrict the contact list here we
can add a condition to only contact the primary domain or domains
listed in the tdc cache, but I don't think that's neccessary.
