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.
