[PATCH net-next v2 04/18] net: dsa: sja1105: use list_add_tail(pos) instead of list_add(pos->prev)

When passed a non-head list element, list_add_tail() actually adds the
new element to its left, which is what we want. Despite the slightly
confusing name, use the dedicated function which does the same thing as
the open-coded list_add(pos->prev).
