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 put_page_bootmem(). In debug mode, there are
following warning:

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

Fixes: dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem")
