As Adrian already explained, changing MAC of WiFi is incorrect
in general, changing MAC of Ethernet is correct way. This was
true before the change as well. It accidentially did work
before for some devices.

I have added entry to updating. The ifconfig_iwn0="" lines in
rc.conf are now just a harmless junk. I don't think that we
need to request users to clean it up.
