Fix: remove keyword defer in the loop to avoid resource leaks

Appearance of defer keyword inside a loop structure may caused resource leaks, it's not recommended to do it although it is in an unit test. Releasing a resource just after finishing using it is the most safe and effective solution, so remove defer is just OK.
