perf, x86: Use helper function in x86_pmu_enable_all()

Use helper function in x86_pmu_enable_all() to minimize access to
x86_pmu.eventsel in the fast path. The counter's msr address is now
calculated using struct hw_perf_event. Later we add code that
calculates the msr addresses with a table lookup which shouldn't be
done in the fast path.
