Instead of requiring KVM_MAX_VCPU_ID to be manually increased every time we increase KVM_MAX_VCPUS, set it to 4*KVM_MAX_VCPUS. This should be enough for CPU topologies where Cores-per-Package and Packages-per-Socket are not powers of 2. In practice, this increases KVM_MAX_VCPU_ID from 1023 to 1152. The only side effect of this change is making some fields in struct kvm_ioapic larger, increasing the struct size from 1628 to 1780 bytes (in x86_64).
