net: lapbether: use netdev_lockdep_set_classes() helper
drivers/net/wan/lapbether.c uses stacked devices.
Like similar drivers, it must use netdev_lockdep_set_classes()
to avoid LOCKDEP splats.
This is similar to commit 9bfc9d65a1dc ("hamradio:
use netdev_lockdep_set_classes() helper")
Fixes: 7e4d784f5810 ("net: hold netdev instance lock during rtnetlink operations")
