This commit fix warning trigger when call synchronize_rcu_tasks_generic() on
early booting and make synchronize_rcu_tasks_generic() directly return when
the rcu_scheduler_active variable is RCU_SCHEDULER_INACTIVE.

Zqiang (2):
  rcu-tasks: Convert RCU_LOCKDEP_WARN() to WARN_ONCE()
  rcu-tasks: Make synchronize_rcu_tasks_generic() no-ops on early
    booting
