[S390] revert add_active_range() usage patch.
Commit 7676bef breaks DCSS support on s390. DCSS needs initialized struct pages to work. With the usage of add_active_range() only the struct pages for physically present pages are initialized. This could be fixed if the DCSS driver would initiliaze the struct pages itself, but this doesn't work too. This is because the mem_map array does not include holes after the last present memory area and therefore there is nothing that could be initialized. To fix this and to avoid some dirty hacks revert this patch for now. Will be added later when we move to a virtual mem_map.
