Subject: [PATCH] ipv6: sr: fix double free of skb after handling invalid SRH

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

Fixes: 7d7efa6a3cea7676f154b9605d66c7bf00e09c87 ("ipv6: implement dataplane support for rthdr type 4 (Segment Routing Header)")
