mm: khugepaged: add trace status description for SCAN_PAGE_HAS_PRIVATE
commit 554913f600b45d73de12ad58c1ac7baa0f22a703 upstream.
Commit 99cb0dbd47a1 ("mm,thp: add read-only THP support for (non-shmem)
FS") introduced a new khugepaged scan result: SCAN_PAGE_HAS_PRIVATE, but
the corresponding description for trace events were not added.
