[PATCH 0/1] MR316: wbemprox: Use return length from NtQuerySystemInformationEx().

[Brendan Shanks (＠bshanks)]

The return length is unlikely to change between the two NtQuerySystemInformationEx calls, but it's possible, and it's more correct to parse the entries with the length from the call where the data was returned.
