[PATCH] winex11.drv: Call XIconifyWindow() after XMapWindow() with a minimized window.

[Zhiyi Zhang]

Mutter always unminimizes a window when handling map requests. So a window could be in
normal state as far as Mutter concerns while Wine mistakenly considers it still minimized.

Fix Disgaea PC black screen after Alt+Tab in fullscreen mode.
