BUG/MEDIUM: lists: Handle 1-element-lists in MT_LIST_BEHEAD().

In MT_LIST_BEHEAD(), explicitely set the next element of the prev to NULL,
instead of setting it to the prev of the next. If we only had one element,
then we'd set the next and the prev to the element itself, and thus it would
make the element appear to be outside any list.
