[PATCH 5.18 117/339] sched/autogroup: Fix sysctl move

[Greg Kroah-Hartman]

From: Peter Zijlstra <peterz@xxxxxxxxxxxxx>

[ Upstream commit 82f586f923e3ac6062bc7867717a7f8afc09e0ff ]

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")
