mm/slab: Dissolve slab_map_pages() in its caller 

Bugzilla: https://bugzilla.redhat.com/2120352

    mm/slab: Dissolve slab_map_pages() in its caller

    The function no longer does what its name and comment suggests, and just
    sets two struct page fields, which can be done directly in its sole
    caller.
