[NETROM] lockdep: fix false positive

Browse Source 
NETROM network devices are virtual network devices encapsulating NETROM
frames into AX.25 which will be sent through an AX.25 device, so form a
special "super class" of normal net devices; split their locks off into a
separate class since they always nest.
