xfrm: Refcount destination entry on xfrm_lookup

We return a destination entry without refcount if a socket
policy is found in xfrm_lookup. This triggers a warning on
a negative refcount when freeeing this dst entry. So take
a refcount in this case to fix it.

This refcount was forgotten when xfrm changed to cache bundles
instead of policies for outgoing flows.
