bootmem, x86: Fix 32bit numa system without RAM on node 0
When 32bit numa is used, free_all_bootmem() will still only go over with
node id 0.
If node 0 doesn't have RAM installed, the lowest populated node
becomes low RAM.
This one fixes BOOTMEM path by iterating over the bdata_list.
-v3: add more comments, and fix bootmem path too.
-v4: seperate from one big patch
