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.
