[PATCH 2/2] ntdll/tests: Align check test correctly clears AC flag.

[Jefferson Carpenter]

Makes sure AC flag is set back to its original value regardless of the 
outcome of the test, so it will not interfere with subsequent tests.

thanks,
Jefferson

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
