Fix VS2013 SDV failures
Fix VS2013 SDV failures

A mis-annotation of some ZwQueryXXX operations is causing SDV to fail
when it notices code in registry.c using the length being passed back
from a failed call. The code is correct according to the documentation of
those functions so this patch suppresses the warnings.
