The comment removed in this patch originally belonged to the
build_zonelists_in_zone_order() function, which was introduced by commit
f0c0b2b808f2 ("change zonelist order: zonelist order selection logic").
Later, commit c9bff3eebc09 ("mm, page_alloc: rip out ZONELIST_ORDER_ZONE")
removed build_zonelists_in_zone_order() but left its comment behind.
Subsequently, commit 9d3be21bf9c0 ("mm, page_alloc: simplify zonelist
initialization") moved the node_order variable into build_zonelists(),
making the comment originally belonged to build_zonelists_in_zone_order()
appear as if it were part of build_zonelists().
Remove this misleading comment.
