net: llc: make empty have static storage duration

Browse Source 
Make @empty have static storage duration (like net/sysctl_net.c does)
to avoid storing a bad pointer, and keep consistent with
__register_sysctl_table @table 'should not be free'd after registration'.

Note that this is _not_ a bug, since size is 0 the pointer will
never get deferenced.
