ioapic: kvm: Skip route updates for masked pins
Masked entries will not generate interrupt messages, thus do no need to be routed by KVM. This is a cosmetic cleanup, just avoiding warnings of the kind qemu-system-x86_64: vtd_irte_get: detected non-present IRTE (index=0, high=0xff00, low=0x100) if the masked entry happens to reference a non-present IRTE.
