  Revert "cgroup: Avoid -Wstringop-overflow warnings" (2023-06-22 08:51:14 -1000)

----------------------------------------------------------------
cgroup: Changes for v6.5

* Whenever cpuset needs to rebuild sched_domain, it walked all tasks looking
  for DEADLINE tasks as they need to be accounted on the new domain. Walking
  all tasks can be expensive and there may not be any DEADLINE tasks at all.
  Task iteration is now omitted if there are no DEADLINE tasks.

* Fixes DEADLINE bandwidth misaccounting after task migration failures.

* When no controller is enabled, -Wstringop-overflow warning is triggered.
  The fix patch added an early exit which is too eager and got reverted for
  now. Will fix later.

* Everything else are minor cleanups.
