[METH]: Fix MAC address handling. 

meth didn't set a valid mac address during probing, but later during
open. Newer kernel refuse to open device with 00:00:00:00:00:00 as mac
address -> dead ethernet. This patch sets the mac address in the probe
function and uses only the mac address from the netdevice struct when
setting up the hardware.
