Steffen Klassert says:

====================
pull request (net): ipsec 2017-10-09

1) Fix some error paths of the IPsec offloading API.

2) Fix a NULL pointer dereference when IPsec is used
   with vti. From Alexey Kodanev.

3) Don't call xfrm_policy_cache_flush under xfrm_state_lock,
   it triggers several locking warnings. From Artem Savkov.

Please pull or let me know if there are problems.
