[NEIGH]: neigh_table_clear() doesn't free stats
neigh_table_clear() doesn't free tbl->stats.
Found by Alexey Kuznetsov. Though Alexey considers this
leak minor for mainstream, I still believe that cleanup
code should not forget to free some of the resources :)
At least, this is critical for OpenVZ with virtualized
neighbour tables.
