[IPSEC]: Lock state when copying non-atomic fields to user-space
This patch adds locking so that when we're copying non-atomic fields such as
life-time or coaddr to user-space we don't get a partial result.
For af_key I've changed every instance of pfkey_xfrm_state2msg apart from
expiration notification to include the keys and life-times. This is in-line
with XFRM behaviour.
The actual cases affected are:
* pfkey_getspi: No change as we don't have any keys to copy.
* key_notify_sa:
+ ADD/UPD: This wouldn't work otherwise.
+ DEL: It can't hurt.
