crypto: engine - Handle the kthread worker using the new API
Use the new API to create and destroy the crypto engine kthread worker. The API hides some implementation details. In particular, kthread_create_worker() allocates and initializes struct kthread_worker. It runs the kthread the right way and stores task_struct into the worker structure. kthread_destroy_worker() flushes all pending works, stops the kthread and frees the structure. This patch does not change the existing behavior except for dynamically allocating struct kthread_worker and storing only the pointer of this structure. It is compile tested only because I did not find an easy way how to run the code. Well, it should be pretty safe given the nature of the change.
