sched: Hide unused sched_update_scaling() 



This function is only used when CONFIG_SMP is enabled, without that there
is no caller and no prototype:

kernel/sched/fair.c:688:5: error: no previous prototype for 'sched_update_scaling' [-Werror=missing-prototypes

Hide the definition in the same #ifdef check as the declaration.

Fixes: 8a99b683 ("sched: Move SCHED_DEBUG sysctl to debugfs")
