Minchan Kim c4549b8711 zsmalloc: remove zspage isolation for migration ... zspage isolation for migration introduced additional exceptions to be dealt with since the zspage was isolated from class list. The reason why I isolated zspage from class list was to prevent race between obj_malloc and page migration via allocating zpage from the zspage further. However, it couldn't prevent object freeing from zspage so it needed corner case handling. This patch removes the whole mess. Now, we are fine since class->lock and zspage->lock can prevent the race.
