vegard.nossum@oracle.com 5b3211dcd4 ieee802154: check device type
I've observed a NULL pointer dereference in ieee802154_del_iface() during
netlink fuzzing. It's the ->wpan_phy dereference here:

        phy = dev->ieee802154_ptr->wpan_phy;

My bet is that we're not checking that this is an IEEE802154 interface,
so let's do what ieee802154_nl_get_dev() is doing. (Maybe we should even
be calling this directly?)
