xfrm_user: fix freeing of xfrm states on acquire
commit 4a135e538962cb00a9667c82e7d2b9e4d7cd7177 upstream.
Commit 565f0fa902b6 ("xfrm: use a dedicated slab cache for struct
xfrm_state") moved xfrm state objects to use their own slab cache.
However, it missed to adapt xfrm_user to use this new cache when
freeing xfrm states.
Fix this by introducing and make use of a new helper for freeing
xfrm_state objects.
Fixes: 565f0fa902b6 ("xfrm: use a dedicated slab cache for struct xfrm_state")
