Fix a lock issue with _NET_CLOSE_WINDOW and WM_DELETE_WINDOW
* exwm.el (exwm--on-ClientMessage): Calling `kill-buffer' directly
from an event context won't work since the DestroyNotify event for a
WM_DELETE_WINDOW request won't be handled until the current event
context terminates.

* exwm-manage.el (exwm-manage--kill-buffer-query-function): Avoid
potential side effects with MapWindow.
