tree/container: Remove child from all lists

When a container is detached, we need to remove it from any lists it may
be part of. We use container_get_siblings to obtain the relevant list,
find our entry and remove it.

If the container is in a later list than the one returned by
container_get_siblings, or is in multiple lists for some reason,
container_detach will fail to remove the container, leaving a dangling
pointer when the container is freed.

Instead of calling container_get_siblings, check and remove the
container from all lists.
