check_ethernet: drop no-op 'duplex' check

This check is misleading: it's not really checking the value of the
'duplex' attribute at all. And even the check it *is* doing isn't really
effective -- for a valid Ethernet device, it will still get 'echo'd a
few lines down, since it
(a) won't be named 'wwan*' or 'lo' and
(b) it won't show up in the 'iw' listing

So since it's basically redundant and confusing, drop it.
