mm: slub: Delete useless parameter of alloc_slab_page()
The parameter @s is useless for alloc_slab_page(). It was added in 2014 by commit 5dfb41750992 ("sl[au]b: charge slabs to kmemcg explicitly"). The need for it was removed in 2020 by commit 1f3147b49d75 ("mm: slub: call account_slab_page() after slab page initialization"). Let's delete it.
