[NETNS]: Fix bad macro definition.
The macro definition is bad. When calling next_net_device with
parameter name "dev", the resulting code is:
struct net_device *dev = dev and that leads to an unexpected
behavior. Especially when llc_core is compiled in, the kernel panics
at boot time.
The patchset change macro definition with static inline functions as
they were defined before.
