netfilter: kill redundant check code in which setting ip_summed value
If the returned csum value is 0, We has set ip_summed with CHECKSUM_UNNECESSARY flag in __skb_checksum_complete_head(). So this patch kills the check and changes to return to upper caller directly. Signed-off-by: Shan Wei <shanwei@cn.fujitsu.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
