xfrm: Remove useless xfrm_audit struct.
Commit f1370cc4 "xfrm: Remove useless secid field from xfrm_audit." changed
"struct xfrm_audit" to have either
{ audit_get_loginuid(current) / audit_get_sessionid(current) } or
{ INVALID_UID / -1 } pair.
This means that we can represent "struct xfrm_audit" as "bool".
This patch replaces "struct xfrm_audit" argument with "bool".
