struct xfrm_user_offload has flags variable that received user input,
but kernel didn't check if valid bits were provided. It caused a situation
where not sanitized input was forwarded directly to the drivers.
For example, XFRM_OFFLOAD_IPV6 define that was exposed, was used by
strongswan, but not implemented in the kernel at all.
As a solution, check and sanitize input flags to forward
XFRM_OFFLOAD_INBOUND to the drivers.
Fixes: d77e38e612a0 ("xfrm: Add an IPsec hardware offloading API")
