Eric Dumazet b3f662ccd3 sch_dsmark: fix invalid skb_cow() usage 
[ Upstream commit aea92fb2e09e29653b023d4254ac9fbf94221538 ]

skb_cow(skb, sizeof(ip header)) is not very helpful in this context.

First we need to use pskb_may_pull() to make sure the ip header
is in skb linear part, then use skb_try_make_writable() to
address clones issues.

Fixes: 4c30719f4f ("[PKT_SCHED] dsmark: handle cloned and non-linear skb's")
