KVM: arm64: PMU: Simplify vcpu computation on perf overflow notification

The way we compute the target vcpu on getting an overflow is
a bit odd, as we use the PMC array as an anchor for kvm_pmc_to_vcpu,
while we could directly compute the correct address.

Get rid of the intermediate step and directly compute the target
vcpu.
