Kieran Bingham 7561e2e376 media: v4l: vsp1: Fix header display list status check in continuous mode

commit 613928e853 upstream.

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.

Fixes: eaf4bfad6a ("v4l: vsp1: Add support for header display lists in continuous mode")
