Miaohe Lin fdacfd7769 khugepaged: fix wrong result value for trace_mm_collapse_huge_page_isolate() 
[ Upstream commit 74e579bf231a337ab3786d59e64bc94f45ca7b3f ]

In writable and !referenced case, the result value should be
SCAN_LACK_REFERENCED_PAGE for trace_mm_collapse_huge_page_isolate()
instead of default 0 (SCAN_FAIL) here.
