[PATCH 0/1] MR10890: winex11.drv: Use hwnd_drop instead of hwnd in x11drv_dnd_drop_event.

[Bernhard Übelacker (＠bernhardu)]

Followup of c3d4665930.

Previously `PostMessageW` received the window handle in `hwnd_prop` through the call to `X11DRV_XDND_SendDropFiles`, but after c3d4665930 `PostMessageW` is called with `hwnd`.
