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

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

Fix sparse warnings:

kernel/sched/fair.c:2596:6: warning: symbol 'task_tick_numa' was not declared. Should it be static?
kernel/sched/fair.c:3570:6: warning: symbol 'sync_entity_load_avg' was not declared. Should it be static?
kernel/sched/fair.c:3583:6: warning: symbol 'remove_entity_load_avg' was not declared. Should it be static?
