sched: sched.c declare variables before they get used

Impact: cleanup, avoid sparse warnings

In linux/sched.h moved out sysctl_sched_latency, sysctl_sched_min_granularity,
sysctl_sched_wakeup_granularity, sysctl_sched_shares_ratelimit and
sysctl_sched_shares_thresh from #ifdef CONFIG_SCHED_DEBUG as these variables
are common for both.

Fixes these sparse warnings:
  kernel/sched.c:825:14: warning: symbol 'sysctl_sched_shares_ratelimit' was not declared. Should it be static?
  kernel/sched.c:832:14: warning: symbol 'sysctl_sched_shares_thresh' was not declared. Should it be static?
  kernel/sched_fair.c:37:14: warning: symbol 'sysctl_sched_latency' was not declared. Should it be static?
  kernel/sched_fair.c:43:14: warning: symbol 'sysctl_sched_min_granularity' was not declared. Should it be static?
  kernel/sched_fair.c:72:14: warning: symbol 'sysctl_sched_wakeup_granularity' was not declared. Should it be static?
