if some function in ndo_stop interface returns failure because of hardware fault, must go on excuting rest steps rather than return failure directly, otherwise will cause memory leak.And bump the timeout for SET_FUNC_STATE to ensure that cmd won't return failure when hw is busy. Otherwise hw may stomp host memory if we free memory regardless of the return value of SET_FUNC_STATE.
