xfrm_user: fix info leak in copy_to_user_policy()
[ Upstream commit 7b789836f434c87168eab067cfbed1ec4783dffd ]
The memory reserved to dump the xfrm policy includes multiple padding
bytes added by the compiler for alignment (padding bytes in struct
xfrm_selector and struct xfrm_userpolicy_info). Add an explicit
memset(0) before filling the buffer to avoid the heap info leak.
