Greg Kroah-Hartman b008f3b255 tty: wipe buffer if not echoing data ...

commit b97b3d9fb5 upstream.

If we are not echoing the data to userspace or the console is in icanon
mode, then perhaps it is a "secret" so we should wipe it once we are
done with it.

This mirrors the logic that the audit code has.
