Subject: [PATCH -next] sched/core: Make some functions static

From: YueHaibing <yuehaibing@...wei.com>

Fix sparse warnings:

kernel/sched/core.c:6576:11: warning: symbol 'max_cfs_quota_period' was not declared. Should it be static?
kernel/sched/core.c:6577:11: warning: symbol 'min_cfs_quota_period' was not declared. Should it be static?
kernel/sched/core.c:6657:5: warning: symbol 'tg_set_cfs_quota' was not declared. Should it be static?
kernel/sched/core.c:6670:6: warning: symbol 'tg_get_cfs_quota' was not declared. Should it be static?
kernel/sched/core.c:6683:5: warning: symbol 'tg_set_cfs_period' was not declared. Should it be static?
kernel/sched/core.c:6693:6: warning: symbol 'tg_get_cfs_period' was not declared. Should it be static?
