raw: use net_hash_mix() in hash function
[ Upstream commit 6579f5ba ] Some applications seem to rely on RAW sockets. If they use private netns, we can avoid piling all RAW sockets bound to a given protocol into a single bucket. Also place (struct raw_hashinfo).lock into its own cache line to limit false sharing. Alternative would be to have per-netns hashtables, but this seems too expensive for most netns where RAW sockets are not used.
