ramips: fix ASUS WL-330N3G MAC address

The ASUS WL-330N and WL-330N3G has the MAC address stored at
offset 4, not 40. This is verified by reading original ASUS
firmware GPL_WL-330N3G_source.1028/user/rc/common_ex.c and
GPL_WL-330N_source.1021/user/rc/common_ex.c.

Tested on WL-330N3G, it now gets the same MAC as is printed on
the label on the router.
