Andi Kleen 0f29e573dd perf/x86/intel: Move PMU ACK to after LBR read ...

With Arch Perfmon v4 the PMU ack unfreezes the LBRs. So we need to do
the PMU ack after the LBR reading, otherwise the LBRs would be polluted
by the PMI handler.

This is a minimal change. In principle the ACK could be moved much later.
