ovs-interface: avoid starting ip[46] configuration more than once

OvsInterface can postpone the stage3_ip[46]_config until the link
actually appears. It ought to restart the stage only when the link
appears, not upon further changes to it (which would trip an assertion
when starting the DHCP client while one already exists).
