crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak
Using completion_done to determine whether the caller has gone
away only works after a complete call. Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.
Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.
