Since commit 9036e917f8 ("{include/}hw/arm: refactor virt PPI logic")
PMU IRQ registration fails for arm64 guests:
[ 0.563689] hw perfevents: unable to request IRQ14 for ARM PMU counters
[ 0.565160] armv8-pmu: probe of pmu failed with error -22
That commit re-defined VIRTUAL_PMU_IRQ to be a INTID but missed a case
where the PMU IRQ is actually referred by its PPI index. Fix that by using
INTID_TO_PPI() in that case.
Fixes: 9036e917f8 ("{include/}hw/arm: refactor virt PPI logic")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1960
