[PATCH 1/2] ieee802154: register a device type for the wpan netdev

[Adriano Cordova <adrianox@gmail.com>]

The cfg802154 netdev notifier never sets a device type, so wpan
interfaces lack a sysfs "type". Mirror cfg80211 by calling
SET_NETDEV_DEVTYPE() in a NETDEV_POST_INIT case with a new
wpan_dev_type.
