media: ipu6: Always call video_device_pipeline_alloc_start()

Browse Source 
Even if a video device is part of a pipeline already,
video_device_pipeline_alloc_start() handles that case gracefully. Don't
explicitly differentiate between video_device_pipeline_start() and
video_device_pipeline_alloc_start() based on the existence of a pipeline.
