[PATCH] kernel/watchdog_hld.c: Fix access percpu in preemptible context

commit 367c820ef08082 ("arm64: Enable perf events based hard lockup detector") reinitilizes lockup detector after arm64 PMU is initialized and provide another chance for access smp_processor_id() in preemptible context. Since hardlockup_detector_event_create() use many percpu relative variable, jus
