wbemprox: Do not call Release() inside wbemprox_cf_CreateInstance().

The Ubisoft overlay version 135 hot patches and hooks wbem_locator_Release(), but crashes if Release() is called inside CoCreateInstance(), a condition that doesn't appear to happen on Windows. So we try to exhibit the same behavior.
