net: use eth_hw_addr_random() and reset addr_assign_type

Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: adapt to renamed eth_hw_addr_random()
