UML net: set addr_assign_type if random_ether_addr() used
Set addr_assign_type correctly to NET_ADDR_RANDOM in case
a random MAC address was generated and assigned to the netdevice.
Return state from setup_etheraddr() about returning a random
MAC address or not and check this state in eth_configure().
