netns xfrm: add struct xfrm_state::xs_net
To avoid unnecessary complications with passing netns around. * set once, very early after allocating * once set, never changes For a while create every xfrm_state in init_net. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
