cgroup: use legacy_name for cgroup v1 disable info

Browse source

cgroup v1 or v2 or both controller names can be passed as arguments to
the 'cgroup_no_v1' kernel parameter, though most of the controller's
names are the same for both cgroup versions. This can be confusing when
both versions are used interchangeably, i.e., passing cgroup_no_v1=io

$ sudo dmesg |grep cgroup
...
cgroup: Disabling io control group subsystem in v1 mounts
cgroup: Disabled controller 'blkio'

Make it consistent across the pr_info()'s, by using ss->legacy_name, as
the subsystem name, while printing the cgroup v1 controller disabling
information in cgroup_init().
