raw: use net_hash_mix() in hash function
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.
