platform: don't treat unrecognized WiMAX devices as Ethernet

If the WiMAX plugin isn't installed, or the WiMAX device isn't
recognized, NetworkManager shouldn't treat the interface as
regular ethernet since the device requires specific setup to
be ready for IP configuration, which of course NetworkManager
can't do because the WiMAX plugin isn't loaded.  Ignore them
instead.
