Florian Westphal 02efdff7e2 xfrm: state: use atomic_inc_not_zero to increment refcount
Once xfrm_state_lookup_byaddr no longer acquires the state lock another
cpu might be freeing the state entry at the same time.

To detect this we use atomic_inc_not_zero, we then signal -EAGAIN to
caller in case our result was stale.
