mm: memcontrol: remove unused mod_memcg_obj_state()

Browse Source 
Since commit 991e767385 ("mm: memcontrol: account kernel stack per
node") there is no user of the mod_memcg_obj_state().  So just remove
it.

Also rework type of the idx parameter of the mod_objcg_state() from int
to enum node_stat_item.
