sched: Fix update_group_power() prototype placement to fix build warning when !CONFIG_SMP
All warnings: In file included from kernel/sched/core.c:85:0: kernel/sched/sched.h:1036:39: warning: 'struct sched_domain' declared inside parameter list kernel/sched/sched.h:1036:39: warning: its scope is only this definition or declaration, which is probably not what you want It's because struct sched_domain is defined inside #if CONFIG_SMP, while update_group_power() is declared unconditionally. Fix this warning by declaring update_group_power() only if CONFIG_SMP=n. Build tested with CONFIG_SMP enabled and then disabled.
