xfrm: Do not parse 32bits compiled xfrm netlink msg on 64bits host
structure like xfrm_usersa_info or xfrm_userpolicy_info has different sizeof when compiled as 32bits and 64bits due to not appending pack attribute in their definition. This will result in broken SA and SP information when user trying to configure them through netlink interface. Inform user land about this situation instead of keeping silent, the upper test scripts would behave accordingly.
