[PATCH v3 13/13] media: ipu6: Always call video_device_pipeline_alloc_start()

[Sakari Ailus <sakari.ailus@linux.intel.com>]

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.
