[PATCH] Move setting of macaddr

I have a test case where I remove and insert another network adapter between two connections to AP.
The interface get the same interface name but switches macadresses between the connections.
When running WPA2 I got a failure in EAPOL negotiation and found out that the reason for this was that the supplicant did not update the macadress in correct place.

Best regards
Johan
