In nested mode, we set up the stage 2 (gpa->hpa)and stage 1 (giova->gpa) separately by vfio_prereg_listener_region_add() and vfio_listener_region_add(). So when marking dirty pages we just need to pay attention to stage 2 mappings. Legacy vfio_listener_log_sync cannot be used in nested stage. This patch adds vfio_prereg_listener_log_sync to mark dirty pages in nested mode.
