winex11.drv: Release window data before calling sync_window_cursor().

Browse source 
This prevents a deadlock between the window data lock and the ntdll loader lock because
sync_window_cursor() eventually may grab the ntdll loader lock. So if another thread already
grabbed the ntdll loader lock and wants to enter the same window data critical section, it will
deadlock.

Fix Youropa (SteamID: 640120) OpenGL launch option launching to a black screen.
