perf, x86: P4 PMU -- update nmi irq statistics and unmask lvt entry properly
In case if last active performance counter is not overflowed at
moment of NMI being triggered by another counter, the irq
statistics may miss an update stage. As a more serious
consequence -- apic quirk may not be triggered so apic lvt entry
stay masked.
