Subject: [PATCH] rcu-tasks: make rcu_tasks_lazy_ms static

The rcu_tasks_lazy_ms are not used outside the file tasks.h, so the
modification is defined as static.

kernel/rcu/tasks.h:1085:5: warning: symbol 'rcu_tasks_lazy_ms' was not declared. Should it be static?

Reported-by: Abaci Robot <abaci@...ux.alibaba.com>
Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=6086
