[PATCH 5/9] vfio/migration: Drop vfio_dma_unmap_dirty_sync_needed()

[Avihai Horon]

There is no need for vfio_dma_unmap_dirty_sync_needed(), as it simply
calls vfio_devices_all_dirty_tracking_started().

Drop vfio_dma_unmap_dirty_sync_needed(), export
vfio_devices_all_dirty_tracking_started() and use it instead.
