sched/numa: Fix task_tick_fair() from disabling numa_balancing
If static branch 'sched_numa_balancing' is enabled, it should kickstart
NUMA balancing through task_tick_numa(). However the following commit:
2a595721a1fa ("sched/numa: Convert sched_numa_balancing to a static_branch")
erroneously disables this.
Fix this anomaly by enabling task_tick_numa() when the static branch
'sched_numa_balancing' is enabled.
