[PATCH 2/3] user32: Destroy window server objects from destroy_thread_windows.

[Jacek Caban]

This ensures that handle validity is consistent between user32 and 
server. Without this patch, during the time between 
destroy_thread_windows() and server noticing that the thread is actually 
destroyed, the state is inconsistent.
