Avoid a few #ifdef's later on.

It does mean that schednuma cannot be enabled or disabled from the command
line (or similarly easy mechanism) and that debugfs must be mounted to
control it. This would be awkward from an admin perspective if they wanted
to force disable schednuma because it hurt their workload for whatever
reason. Yes, they can disable it with an init script of some sort but
there will be some moaning.
