The problem I am trying to fix with this patch occurs during connection
teardown. See for example setupapi.SetupInstallServicesFromInfSectionW, where
the error code is set before calling CloseServiceHandle(), which will send
additional RPC messages. The alternative solutions would be:
* Only restore error code for CloseServiceHandle()
* Restructure setupapi code to set the error as a last step, after calling CloseServiceHandle.
