device: when activating without cloned-mac-address, set the permanent one

Browse source 
Don't rely on what's already on the device. It could be that the MAC address
set on the device is not meaningful -- the NM crashed while two devices were
teamed together and now they have the same hardware address and now it's
impossible to bond them with mode=5.
