Miaohe Lin cec22fc529 hugetlb_cgroup: fix wrong hugetlb cgroup numa stat
[ Upstream commit 2727cfe4072a35ce813e3708f74c135de7da8897 ]

We forget to set cft->private for numa stat file.  As a result, numa stat
of hstates[0] is always showed for all hstates.  Encode the hstates index
into cft->private to fix this issue.
