[PATCH 0/1] MR1607: winex11.drv: Release window data before calling sync_window_cursor().

[Zhiyi Zhang (＠zhiyi)]

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.
