[KJ] net/wan/lapbether.c:check return code of

[walter harms]

hi all,
if the patches for bond_main.c,bpqether.c,dlci.c,lapbether.c and
pppoe.c are applied no more uncecked register_netdevice_notifier()
should be exist. i did a test compile with all patches and found no
ill effects.

check return code of register_netdevice_notifier.
