Subject: [PATCH v2 -next] sched/core: Make some functions static

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

Fix sparse warnings:

kernel/sched/core.c:6524:11: warning: symbol 'min_cfs_quota_period' was not declared. Should it be static?
kernel/sched/core.c:6604:5: warning: symbol 'tg_set_cfs_quota' was not declared. Should it be static?
kernel/sched/core.c:6617:6: warning: symbol 'tg_get_cfs_quota' was not declared. Should it be static?
kernel/sched/core.c:6630:5: warning: symbol 'tg_set_cfs_period' was not declared. Should it be static?
kernel/sched/core.c:6640:6: warning: symbol 'tg_get_cfs_period' was not declared. Should it be static?
