xfrm: Refcount destination entry on xfrm_lookup
[ Upstream commit fbd5060875d25f7764fd1c3d35b83a8ed1d88d7b ]
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.
