4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Lebrun <[email protected]>


[ Upstream commit 95b9b88d2da5e43e025400afcb492643933bf858 ]

The icmpv6_param_prob() function already does a kfree_skb(),
this patch removes the duplicate one.

Fixes: 1ababeba4a21f3dba3da3523c670b207fb2feb62 ("ipv6: implement dataplane 
support for rthdr type 4 (Segment Routing Header)")
