geneve: Store struct sock in struct geneve_sock.

Browse source

geneve does not need to access struct socket itself in the fast
path; it only reads struct sock, and struct socket is only used for
tunnel setup and teardown.

Let's store struct sock directly in struct geneve_sock.

__geneve_sock_release() frees geneve_sock with kfree_rcu(), so
geneve no longer needs synchronize_rcu() in udp_tunnel_sock_release().
