Peter Zijlstra c2872d381f perf/x86/ibs: Add IBS interrupt to the dynamic throttle
Interrupt throttling is normally only done against
sysctl_perf_event_sample_rate. This means that if that number is too
high (for whatever reason) you can lock up your machine.

We have, however, a dynamic throttling scheme too, but for that to
work, we need to add a callback to the interrupt handler, IBS did not
have this, so add it.
