In nested mode, we set up the stage 2 and stage 1 separately. In my opinion, vfio_memory_prereg_listener is used for stage 2 and vfio_memory_listener is used for stage 1. So it feels weird to call the global_log_start/stop interface in vfio_memory_listener to switch dirty tracking, although this won't cause any errors. Add global_log_start/stop interface in vfio_memory_prereg_listener can separate stage 2 from stage 1.
