net: Fix one possible memleak in ip_setup_cork It would allocate memory in this function when the cork->opt is NULL. But the memory isn't freed if failed in the latter rt check, and return error directly. It causes the memleak if its caller is ip_make_skb which also doesn't free the cork->opt when meet a error. Now move the rt check ahead to avoid the memleak. Signed-off-by: Gao Feng <gfree.wind@vip.163.com> Signed-off-by: David S. Miller <davem@davemloft.net>
