Florian Westphal ae33786f73 xfrm: policy: only use rcu in xfrm_sk_policy_lookup
Don't acquire the readlock anymore and rely on rcu alone.

In case writer on other CPU changed policy at the wrong moment (after we
obtained sk policy pointer but before we could obtain the reference)
just repeat the lookup.
