tty: serial - fix tty back references in termios
One or two drivers go poking back into the tty from the termios setting
routine in unsafe ways. We don't need to pass the tty down because the
[ab]users are just using it to get at things they can get at anyway.
This leaves low_latency setting to sort out along with set_ldisc use.
