device: don't set invalid ip-iface

Browse Source 
Now that every call to nm_device_set_ip_iface() and nm_device_set_ip_ifindex()
is checked, and setting an interface that does not exist causes the device
state to fail, we no longer need to allow setting an ip-iface if we are
unable to retrieve the ip-ifindex.
