[resend PATCH 1/3] Avoid undefined result in ntdll_wcstoumbs() in case of error.
Undefined result is due to RtlUnicodeToUTF8N() not setting output length on error which is a correct behaviour according to existing tests. 'Planet Zoo' is affected which passes NULL object name buffer to NtCreateFile().

Hi, While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?
