[Win32] Fix swapped arguments in readRegistryDwords null checks

Objects.requireNonNull(T obj, String message) takes the object to check
as the first argument. The two calls in readRegistryDwords had the
arguments reversed, causing the non-null string literals "key" and
"valueName" to be checked instead of the actual key and valueName
variables, making both null guards complete no-ops.
