sched/autogroup: Fix sysctl move

Ivan reported /proc/sys/kernel/sched_autogroup_enabled went walk-about
and using the noautogroup command line parameter would result in a
boot error message.

Turns out the sysctl move placed the init function wrong.

Fixes: c8eaf6ac76f4 ("sched: move autogroup sysctls into its own file")
