Subject: [PATCH net-next 1/9] can: raw: raw_sendmsg(): remove not needed setting of skb->sk

The skb in raw_sendmsg() is allocated with sock_alloc_send_skb(),
which subsequently calls sock_alloc_send_pskb() -> skb_set_owner_w(),
which assigns "skb->sk = sk".

This patch removes the not needed setting of skb->sk.
