Maybe relaxing the check and allow ip link to move a wireless netdev

really do not know if this is worth it, but for some simpler container
cases it could be beneficial if RTNL can be used instead of having to
go through nl80211.

The thought crossed my mind, but

1) it's relatively complex, though by no means impossible
2) it still moves more than you bargained for, since in theory the wiphy
could be
   used to create new interfaces etc.

That said, I'm much more inclined to believe such a patch would be
worthwhile than the original.
