mm/hugetlb_cgroup: identify the legacy using cgroup_subsys_on_dfl()

Patch series "mm/hugetlb_cgroup: rework on cftypes", v3.

This patchset provides an intuitive view of the control files through
static templates of cftypes.  This improves the readability of the code.  


This patch (of 3):

Currently the numa_stat file encodes 1 into .private using the micro
MEMFILE_PRIVATE() to identify the legacy.  Actually, we can use
cgroup_subsys_on_dfl() instead.  This is helpful to handle .private in the
static templates in the next patch.
