[PATCH] pty: Remove redundant itty reset

[Peter Hurley]

port->itty has already been reset by release_tty() before
pty_cleanup() is called.

Call stack:
release_tty()
  tty_kref_put()
    queue_release_one_tty()
      release_one_tty() : workqueue
        tty->ops->cleanup()
          pty_cleanup()
