TTY: remove tty driver re-set from tty_reopen
This is from tty_reopen: struct tty_driver *driver = tty->driver; ... tty->driver = driver; and it doesn't make sense at all. The driver is intended to be set in initialize_tty_struct from tty_init_dev (initial open). So this set in tty_reopen is not needed.
