platform: always try to refetch new ethernet links

Browse source 
Due to a kernel bug [1], we sometimes receive spurious NEWLINK
messages after a wifi interface has disappeared. Since the link is not
present anymore we can't determine its type and thus it will show up
as a Ethernet one, with no address specified.  Request the link again
to check if it really exists.
