xfrm/compat: Cleanup WARN()s that can be user-triggered
Replace WARN_ONCE() that can be triggered from userspace with pr_warn_once(). Those still give user a hint what's the issue. I've left WARN()s that are not possible to trigger with current code-base and that would mean that the code has issues: - relying on current compat_msg_min[type] <= xfrm_msg_min[type] - expected 4-byte padding size difference between compat_msg_min[type] and xfrm_msg_min[type] - compat_policy[type].len <= xfrma_policy[type].len (for every type) Reported-by: syzbot+834ffd1afc7212eb8147@syzkaller.appspotmail.com Fixes: 5f3eea6b7e8f ("xfrm/compat: Attach xfrm dumps to 64=>32 bit translator") Cc: "David S.
