The node_array[RTE_ACL_DFA_SIZE] is assigned to
RTE_ACL_IDLE_NODE and is used as a node of
RTE_ACL_NODE_SINGLE type, but it is currently based
on the implementation of idle arrays with a value of all
0 to point to itself, which is unsafe, if the value of the
idle array is not 0, it will produce undefined behavior,
so it needs to be given node_array[RTE_ACL_DFA_ SIZE]
plus RTE_ACL_QUAD_SINGLE.
