If static branch sched_numa_balancing is enabled, it should kickstart
numa_balancing through task_tick_numa(). However Commit 2a1ed24
("sched/numa: Convert sched_numa_balancing to a static_branch")
erroneously disables this.Fix this anomaly by enabling task_tick_numa when static branch sched_numa_balancing is enabled.
