  The memory pointed by lpm->rules_tbl should also be freed
when memory malloc for tbl8 fails in rte_lpm_create_v1604( ).
And the memory pointed by lpm->tbl8 should also be freed
when the lpm object is freed in rte_lpm_free_v1604( ).

Fixes: f1f7261838b3 ("lpm: add a new config structure for IPv4")
