Applied, but I had to do this by hand since it's not cleanly against
net-2.6.19:

>  	*res = sock;
>  	security_socket_post_create(sock, family, type, protocol, kern);

security_socket_post_create() returns an error code in the
current tree, and does a goto out_release; on error.

So I defer the *res = sock; until we know that this security
hook ran error-less.
