Dan Williams cd5da9bf88 wired: move hardware address handling back to NMDeviceWired subclasses 
The code flow is actually somewhat simpler this way since the
subclasses don't have to ask NMDeviceWired for the address
every time.  Plus then NMDeviceWired doesn't have to know
anything about its subclasses in the constructor.
