- Fixed to wait for dhcp/ipv6 under systemd again.
Fixed regression caused by bnc#785240, bnc#780644 fixes to not
discard the dhcp/ipv6 dupplicate address detection in progress
error codes under systemd completely, but wait until dhcp/ipv6
dad finished or the WAIT_FOR_INTERFACES timeout is reached and
then discard in the status returned to systemd (bnc#808718).
It caused failures of other services trying to bind tentative
IPv6 addresses, e.g. in mixed dhcp4 / static IPv6 setups.
Thanks to Rolf Eike Beer for the report/tests/debug outputs.
