When adding a new xfrm state, the data provided via struct xfrm_state
is stored in network byte order. This needs to be taken into
consideration when exporting the SAs data to userspace via debugfs,
otherwise the content will depend on the system endianness. Fix this by
converting all multi-byte fields from network to host order.
Also fix the selftest script which was expecting the data as exported by
a little-endian system, which was inverted.

Fixes: 2766a11161cc ("selftests: rtnetlink: add ipsec offload API test")
