perf/x86/intel: Fix Haswell CYCLE_ACTIVITY.* counter constraints
Some of the CYCLE_ACTIVITY.* events can only be scheduled on counter 2. Due to a typo Haswell matched those with INTEL_EVENT_CONSTRAINT, which lead to the events never matching as the comparison does not expect anything in the umask too. Fix the typo.
