Fix handling of skip_permission_denied on windows; after converting the return value of GetLastError() to a standard error_code, ec.value() is in the standard errc range, not a native windows error code. This was missed in 156180727d6c347eda3ba749730707acb8a48093. The directory "C:\System Volume Information" does seem to exist and have these properties on most relevant contempory setups.
