audit: fix incorrect set of audit_sock
NETLINK_CB(skb).sk is the socket of user space process, netlink_unicast in kauditd_send_skb wants the kernel side socket. Since the sk_state of audit netlink socket is not NETLINK_CONNECTED, so the netlink_getsockbyportid doesn't return -ECONNREFUSED. And the socket of userspace process can be released anytime, so the audit_sock may point to invalid socket. this patch sets the audit_sock to the kernel side audit netlink socket.
