vbo/dlist: reset vertex_store::used in reset_counters 

This means that each list will start writing its vertices at index 0.

The previous mode (append) was useful in the past when the vertices
were written directly to a mapped-buffer object.

Now that there's an intermediate storage in RAM, the added complexity
of the append-mode has no value so drop it.
