Stop filtering filesystem operations.
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
This method detaches the filter, causing the class's system driver to stop filtering filesystem operations.
The WaitForDetach parameter specifies whether this method should execute synchronously, blocking until the filter has been detached; or asynchronously, returning immediately. The FilterStop event will fire (in either case) once the filter has been detached.
