drivers: perf: Fix wrong put_cpu() placement
Unfortunately, the wrong patch version was merged which places the
put_cpu() after enabling a static key, which is not safe as pointed by
Will [1], so move put_cpu() before to avoid this.
Fixes: 2840dadf0dde ("drivers: perf: Fix smp_processor_id() use in preemptible code")
