[O] [PATCH] Bug fix: delete indirect buffer's window only when it exists.

[Muchenxuan Tong]

Bug fix: delete indirect buffer's window only when it exists.
* org-agenda.el (org-agenda-quit): Delete indirect buffer's window
only when it exists.

When indirect buffer's window doesn't exist, the original logic will
delete the current window.
