media: v4l: vsp1: Fix header display list status check in continuous mode
To allow dual pipelines utilising two WPF entities when available, the VSP was updated to support header-mode display list in continuous pipelines. A small bug in the status check of the command register causes the second pipeline to be directly afflicted by the running of the first; appearing as a perceived performance issue with stuttering display. Fix the vsp1_dl_list_hw_update_pending() call to ensure that the read comparison corresponds to the correct pipeline.
