[PATCH 4/8] mm/bootmem_info: remove call to kmemleak_free_part_phys()

The call to kmemleak_free_part_phys() was added in 2022 in
commit dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in
put_page_bootmem").

In 2025, commit b2aad24b5333 ("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.
