Peter Hurley d8c1f929aa tty: Only guarantee termios read safety for throttle/unthrottle ...

No tty driver modifies termios during throttle() or unthrottle().
Therefore, only read safety is required.

However, tty_throttle_safe and tty_unthrottle_safe must still be
mutually exclusive; introduce throttle_mutex for that purpose.
