That's more of the system problem than anything else, kernel itself does
not mount cgroups anywhere, that's usually done it the boot process and
it ends up under /sys/fs/cgroups/ on most of the recent distributions.
It looks like something has mounted cgroups over the /dev/cgroup on your
system, it's up to you to figure out why is it mounted there.
