The call to kmemleak_free_part_phys() was added in 2022 in commitdd0ff4d12d("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem"). In 2025, commitb2aad24b53("mm/memmap: prevent double scanning of memmap by kmemleak") started to use MEMBLOCK_ALLOC_NOLEAKTRACE when allocating the memmap to skip the kmemleak_alloc_phys() in the buddy. So remove the call to kmemleak_free_part_phys(). If this would still be required for other purposes, either free_reserved_page() should take care of it, or selected users.
