net: Allow xfrm_user_net_exit to batch efficiently. xfrm.nlsk is provided by the xfrm_user module and is access via rcu from other parts of the xfrm code. Add xfrm.nlsk_stash a copy of xfrm.nlsk that will never be set to NULL. This allows the synchronize_net and netlink_kernel_release to be deferred until a whole batch of xfrm.nlsk sockets have been set to NULL. Signed-off-by: Eric W.
