Eric Dumazet ca0edb131b ieee802154: 6lowpan: fix possible NULL deref in lowpan_device_event() 
A tun device type can trivially be set to arbitrary value using
TUNSETLINK ioctl().

Therefore, lowpan_device_event() must really check that ieee802154_ptr
is not NULL.

Fixes: 2c88b5283f ("ieee802154: 6lowpan: remove check on null")
