tty: do not check tty_unregister_driver's return value
These drivers check tty_unregister_driver return value. But they don't
handle a failure correctly (they free the driver in any case). So stop
checking tty_unregister_driver return value and remove also the prints.
In the next patch, tty_unregister_driver's return type will be switched
to void.
