dmatest: cancel thread immediately when asked for
If user have the timeout alike issues and wants to cancel the thread immediately, the current call of wait_event_freezable_timeout is preventing to this until timeout is expired. Thus, user will experience the unnecessary delays. Adding kthread_should_stop() check inside wait_event_freezable_timeout() solves that.
