Thomas Gleixner b4f75d44be perf/core: Remove bogus UP_CANCELED hotplug state ...

If CPU_UP_PREPARE fails the perf hotplug code calls perf_event_exit_cpu(),
which is a pointless exercise. The cpu is not online, so the smp function
calls return -ENXIO. So the result is a list walk to call noops.

Remove it.
