commit 028725e73375a1ff080bbdf9fb503306d0116f28 upstream.
commit dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem") fix an overlaps existing problem of kmemleak. But the problem still existed when HAVE_BOOTMEM_INFO_NODE is disabled, because in this case, free_bootmem_page() will call free_reserved_page() directly.
Fix the problem by adding kmemleak_free_part() in free_bootmem_page() when HAVE_BOOTMEM_INFO_NODE is disabled.
