Subject: memcg: fix typo in kmemcg cache walk macro
The macro for_each_memcg_cache_index contains a silly yet potentially
deadly mistake. Although the macro parameter is _idx, the loop tests are
done over i, not _idx.
This hasn't generated any problems so far, because all users use i as a
loop index. However, while playing with an extension of the code I ended
using another loop index and the compiler was quick to complain.
Unfortunately, this is not the kind of thing that testing reveals =(
