target/arm/kvm: pmu: improve error handling
If a KVM PMU init or set-irq attr call fails we just silently stop
the PMU DT node generation. The only way they could fail, though,
is if the attr's respective KVM has-attr call fails. But that should
never happen if KVM advertises the PMU capability, because both
attrs have been available since the capability was introduced. Let's
just abort if this should-never-happen stuff does happen, because,
if it does, then something is obviously horribly wrong.
