The point we assign dev->wireless_handlers at is too
late, we need to do that before netdev_register_kobject()
gets called, so use the new NETDEV_PRE_INIT notifier.
The result of adding wireless_handlers too late is the
disappearance of /sys/class/net/wlan0/wireless which a
bunch of distro scripts still require.

Ignore please, I have a better, self-contained fix.
