Re: [PATCH v2 0/5] MR9332: combase: Implement RoOriginateError.

[Vibhav Pant (＠vibhavp)]

v2:
* Fix leak in `IRestrictedErrorInfo::Release`.
* Fix potential leak in RoOriginateErrorW if `set_error_info` fails.
* Use SysAllocStringLen in `IRestrictedErrorInfo::GetErrorDetails` and `IErrorInfo::GetDescription`, as error strings don't contain embedded NULs.
* Return S_FALSE in `GetRestrictedErrorInfo` if the current error object didn't support `IRestrictedErrorInfo`.
