net: ipv4: Fix wrong type conversion from hint to rt in ip_route_use_hint()
We can't cast sk_buff to rtable by (struct rtable *)hint. Use skb_rtable(). Fixes: 02b24941619f ("ipv4: use dst hint for ipv4 list receive") Signed-off-by: Miaohe Lin <linmiaohe@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
