atheros eth: 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.
Fix error handling in atl1c_probe(). If atl1c_read_mac_addr()
couldn't get the hw mac address, and a random mac address get
set return the error code. Don't go to err_eeprom in
atl1c_probe(), use the generated MAC address in this case.
Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.
v2: use bitops
