When we set mac address, software mac address in system and hardware mac
address all need to be updated. Current eth_mac_addr() doesn't allow
callers to implement error handling nicely.

This patch split eth_mac_addr() to prepare part and real commit part,
then we can prepare first, and try to change hardware address, then do
the real commit if hardware address is set successfully.

Feel free to make yourself author and put me just as Suggested-by:.  I
posted pseudo-code but didn't write the patch or test it, so it's fair
to say that credit goes to you. :)
