ieee802154: 6lowpan: remove check on null

Browse Source 
This patch removes one check on null which should be already done by
checking before for ARPHRD_IEEE802154. All ARPHRD_IEEE802154 and
ARPHRD_IEEE802154_MONITOR should have wdev->ieee802154_ptr, where
ARPHRD_IEEE802154 is currently a node interface only.
