perf/x86/intel: Fix Core2,Atom,NHM,WSM cycles:pp events

commit 517e6341 upstream.

Ingo reported that cycles:pp didn't work for him on some machines.

It turns out that in this commit:

  af4bdcf6 perf/x86/intel: Disallow flags for most Core2/Atom/Nehalem/Westmere events

Andi forgot to explicitly allow that event when he
disabled event flags for PEBS on those uarchs.
