advapi32: CryptEnumProviders doesn't return pdwProvType when szProvName is NULL.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=56305
The call like below doesn't changes dwType.
DWORD dwIndex = 0;
DWORD dwType = -1;
DWORD cbName = -1;
CryptEnumProviders(dwIndex, NULL, 0, &dwType, NULL, &cbName);
The whole point of the call is to iterate over all providers looking for a specific dwType.
