Reference count leaking of both module and sock were found: - When a detached file were closed, its sock refcnt from device were not released, solving this by add the sock_put(). - The module were hold or drop unconditionally in TUNSETPERSIST, which means we if we set the persist flag for N times, we need unset it for another N times. Solving this by only hold or drop an reference when there's a flag change and also drop the reference count when the persist device is deleted.
