perf: Enable updating exclude_idle events at idle

Browse source 
Commit 573979dee2 ("perf: Add support for exclude_idle attribute")
does a register_idle_notifier call so that exclude_idle events
are updated when a CPU goes idle. This commit fixes a bug which
causes unregister_idle_notifier to be erroneously called.
