[PULL 03/21] target/arm/kvm: Set PMU for host only when available

[Peter Maydell]

From: Akihiko Odaki <akihiko.odaki@daynix.com>

target/arm/kvm.c checked PMU availability but unconditionally set the
PMU feature flag for the host CPU model, which is confusing. Set the
feature flag only when available.
