Quick fix for crashing menus

[Jukka Heinonen]

Here is a simple patch that prevents menus from crashing 
(see wine-devel for details). This patch is quite hacky but
it does fix a single real, verified problem and likely a bunch
of unverified problems. Proper fix would be quite complicated,
at least process_cooked_mouse_message and process_raw_mouse_message
need to be redesigned and possibly also wineserver message queue
routines.

Changelog:
  Prevent some illegal messages when mouse has been captured.
