    drm/i915/pmu: Initialise the spinlock before registering

    As the GT may be running in parallel with the module initialisation
    code, we may enter i915_pmu_gt_parked() as we are executing
    i915_pmu_register(). We have to init the spinlock before we mark
    pmu.event_init so that it is available for use by i915_pmu_gt_parked()
    (which may run as soon as event_init is set).
