KVM: x86: consolidate different ways to test for in-kernel LAPIC
Different pieces of code checked for vcpu->arch.apic being (non-)NULL, or used kvm_vcpu_has_lapic (more optimized) or lapic_in_kernel. Replace everything with lapic_in_kernel's name and kvm_vcpu_has_lapic's implementation. Reviewed-by: Radim Krčmář <rkrcmar@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
