Subject: TTY: pty, fix compilation warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When CONFIG_UNIX98_PTYS is unset, we see this warning in pty:
  drivers/tty/pty.c:409:13: warning: ‘pty_unix98_shutdown’ defined but not used

Fix that by moving the function to a section which depends on that
config.
