Callback for a Provider when Activate-level interest is removed for an Object and Interface. This callback is called whenever an Activate-level interest request for the given Object ID and Interface ID is cancelled or times out. This does not always mean the given Object and Interface no longer needs to be active; use DOFSystem_IsInterestRequested to check if it is still needed. This call is responsible for removing the binding(s) added by the previous call to Activate. If the interfaceID is the wildcard IID, then the application can check whether any specific Interface IDs are still active for the Object via DOFSystem_IsInterestRequested.
This callback may be NULL to ignore notification of interest removal.
