The sensor is guaranteed not to be streaming when the runtime PM resume handler is called, as the resume handler is only called from the .s_stream() operation when starting streaming. Similarly, the sensor has been stopped when the runtime PM suspend handler is called. There is thus no need for manual stream start/stop from the runtime PM handlers. Drop them. The streaming field of the driver's private structure is now unused, drop it as well.
