From: Johannes Berg <johannes.berg@xxxxxxxxx>
The wext call SIOCGIWMODE appears to be frequently used by
the QT libraries to determine whether or not a netdev is
wireless and here multi-link makes no difference. Also,
SIOCGIWNAME is completely static.
Allow these calls without a warning since these won't be
going away if we allow them here now.

Really not sure this is the right thing to do. On the one
hand it's easy, but on the other hand we've been disabling
WEXT completely for drivers Intel ships, and nobody has
complained about that in years.
