[reactos] 01/03: [KMTESTS:IO] Rewrite IoDeviceInterface kmtest Add new kernel-mode test for Device Interface functions, based on the patch by Mark Jansen. The previous one was buggy and crashed even on Windows. The new one doesn't fail, and works without bugs. Although there is missing one test case (for IoRegisterDeviceInterface). Also perhaps IoRegister/UnregisterPlugPlayNotification testcases should be keept, if they correspond to Device Interface functions. CORE-17361
