cisco/enic: use eth_hw_addr_random() instead of random_ether_addr()

Use dev_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.

v3: adapt to net-next
v2: use bitops, adapt to eth_hw_addr_random(), add a comment
