[PATCH 0/2] MR1099: win32u: Use session BaseNamedObjects for display_device_init mutex.

[Rémi Bernon (＠rbernon)]

The mutex is also used in user32, gdi32, and winevulkan, where it is
opened through kernel32, which opens it from the session directory.

I believe this will fix the d3drm spurious errors, and hopefully the
ddraw ones too, but I haven't investigated these as the test takes
much longer to run.
