Since kmemleak_alloc_phys() rather than kmemleak_alloc() was called from
memblock_alloc_range_nid(), kmemleak_free_part_phys() should be used to
delete kmemleak object in free_bootmem_page(). In debug mode, there are
following warning:

 kmemleak: Partially freeing unknown object at 0xffff97345aff7000 (size 4096)

Fixes: 028725e73375 ("bootmem: remove the vmemmap pages from kmemleak in free_bootmem_page")
