If we're doing the pre-dump command we don't have the tasks' IDs collected, so we have the current_ns_mask uninitilized. Thus we create parasite transport socket in criu's namespace always and pre-dump of task, sitting in foreing net namespace may hang. From the "performance" point of view, it's easier to always create transport socket in victim's namespace, rahter than getting the current_ns_mask.
