mm/page_alloc.c: silence build_all_zonelists() section mismatch 

The memory hotplug case involves calling to build_all_zonelists() which
in turns calls in to setup_zone_pageset().  The latter is marked
__meminit while build_all_zonelists() itself has no particular
annotation.  build_all_zonelists() is only handed a non-NULL pointer in
the case of memory hotplug through an existing __meminit path, so the
setup_zone_pageset() reference is always safe.

The options as such are either to flag build_all_zonelists() as __ref (as
per __build_all_zonelists()), or to simply discard the __meminit
annotation from setup_zone_pageset().
