batman-adv: Use proper name for fragments list head
The batman-adv codebase is using "list" for the list node (prev/next) and <list content descriptor>+"_list" for the head of a list. Not using this naming scheme can up in confusions because list_head is used for both the head of the list and the list node (prev/next) in each item of the list.
