ramips: dir-3040-a1: fix MAC address assignment

The dtsi used handles a bunch of non-DBDC platforms where the
assignments are correct. The 3040-a1 is different as there are 3 instead
of 2 wifi interfaces and WAN needs to be incremented by 1.

Remove userspace wifi assignmwent which was needed before per band nvmem
was supported.
