After the request is finished, SEC driver's call back will identify the 'fake busy' flag, and notifies the user that hardware is not busy now by calling user's call back function. Now, a request sent into busy hardware will be cached in the SEC queue's backlog, return '-EBUSY' to user. After the request being finished, the cached requests will be processed in the call back function. to notify the corresponding user that SEC queue can process more requests.
