mm/thp: fix doc for transparent huge zero page

Transparent huge zero page is used during the page fault instead of in
khugepaged.

  # ls /sys/kernel/mm/transparent_hugepage/
  defrag  enabled  khugepaged  use_zero_page
  # ls /sys/kernel/mm/transparent_hugepage/khugepaged/
  alloc_sleep_millisecs  defrag  full_scans  max_ptes_none  pages_collapsed  pages_to_scan  scan_sleep_millisecs

This patch corrects the documentation just like the codes done.

+echo 0 >/sys/kernel/mm/transparent_hugepage/use_zero_page

 khugepaged will be automatically started when
 transparent_hugepage/enabled is set to "always" or "madvise, and it'll
