WdfIoQueueRetrieveFoundRequest rule (kmdf)

The WdfIoQueueRetrieveFoundRequest rule specifies that WdfIoQueueRetrieveFoundRequest method is called only after WdfIoQueueFindRequest is called and returned STATUS_SUCCESS and no WdfObjectDereference is called on the same request.

If WdfIoQueueFindRequest returns STATUS_SUCCESS it increments the reference count of the output request object, the driver must call WdfObjectDereference after it has finished using this request handle.
