memcg: fix page_cgroup fatal error in FLATMEM
Now, SLAB is configured in very early stage and it can be used in
init routine now.
But replacing alloc_bootmem() in FLAT/DISCONTIGMEM's page_cgroup()
initialization breaks the allocation, now.
(Works well in SPARSEMEM case...it supports MEMORY_HOTPLUG and
size of page_cgroup is in reasonable size (< 1 << MAX_ORDER.)
This patch revive FLATMEM+memory cgroup by using alloc_bootmem.
In future,
We stop to support FLATMEM (if no users) or rewrite codes for flatmem
completely.But this will adds more messy codes and overheads.
