Subject: ipv6: sr: fix double free of skb after handling invalid SRH
From: David Lebrun <david.lebrun@uclouvain.be>
[ 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)")
