net: xfrm: fix memory leak in xfrm_user_rcv_msg
Syzbot reported memory leak in xfrm_user_rcv_msg(). The
problem was is non-freed skb's frag_list.
In skb_release_all() skb_release_data() will be called only
in case of skb->head != NULL, but netlink_skb_destructor()
sets head to NULL. So, allocated frag_list skb should be
freed manualy, since consume_skb() won't take care of it
Fixes: 5106f4a8acff ("xfrm/compat: Add 32=>64-bit messages translator")
