memcg: disable move charge in no mmu case
In commit 02491447 ("memcg: move charges of anonymous swap"), I tried to disable move charge feature in no mmu case by enclosing all the related functions with "#ifdef CONFIG_MMU", but the commit places these ifdefs in wrong place. (it seems that it's mangled while handling some fixes...) This patch fixes it up.
