Goodbye REGISTRY_ERROR bsod!

• Change UserMode -> KernelMode in ObReferenceObject*() calls, because that calls failed
• Remove Cm-specific hack from Ob "advapi32_winetest.exe registry" shows 0 failures on the first run and 2 failures on further runs. I suppose there might be a leakage in the CM. To be investigated further (or wait till complete Cm rewrite in October).

Still regedit crashes when trying to open a key that contains one or more values.
