Map clone was written before we introduced reference counts for maps and dsos, so all that was needed was just a copy and then we would insert it into the new map_groups instance. Fix it by, after copying, initializing the map->refcnt, grabbing a struct dso refcount and resetting pointers that may be used to determine if a map, when deleted, is in a rb_tree.
