mm: remove obsoleted alloc_pages cpuset comment 



When a cpuset's nodemask is updated, all attached tasks have their cached
task->mems_allowed updated by a heap instead of requiring an explicit call
to cpuset_update_task_memory_state(), which has since been removed in
58568d2a ("cpuset,mm: update tasks'
mems_allowed in time").

Remove the obsoleted comment from the page allocator.
