Code is already using wl_list_init to have the construction of unlinked
items in a stable state so that they can be destroyed with wl_list_remove.
A problem is it is easy to write code that calls wl_list_remove during
the structures life and miss that you need to reset with wl_list_init
for when it is later destroyed.
Having wl_list_remove place items in this unlinked state makes the
destruction safe (and makes quite a few lines of code redundant.)
