Tejun Heo 03db771615 Revert "cgroup: enable cgroup_get_from_file() on cgroup1"
This reverts commit f3a2aebdd6fb90e444d595e46de64e822af419da.

The commit enabled looking up v1 cgroups via cgroup_get_from_file().
However, there are multiple users, including CLONE_INTO_CGROUP, which have
been assuming that it would only look up v2 cgroups. Returning v1 cgroups
breaks them.

Let's revert the commit and retry later with a separate lookup interface
which allows both v1 and v2.
