sched/tune: access schedtune_initialized under CGROUP_SCHEDTUNE
schedtune_initialized is protected by CONFIG_CGROUP_SCHEDTUNE, but
is being used without CONFIG_CGROUP_SCHEDTUNE being defined. Add
appropriate ifdefs around the usage of schedtune_initialized to
avoid a compilation error when CONFIG_CGROUP_SCHEDTUNE is not
defined.
