[S390] revert add_active_range() usage patch.

Commit 7676bef9c183fd573822cac9992927ef596d584c 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.
