kvm: x86: check kvm_apic_sw_enabled() is enough
On delivering irq to apic, we iterate on vcpu and do the check like
this:
kvm_apic_present(vcpu)
kvm_lapic_enabled(vpu)
kvm_apic_present(vcpu) && kvm_apic_sw_enabled(vcpu->arch.apic)
Since we have already checked kvm_apic_present(), it is reasonable to
replace kvm_lapic_enabled() with kvm_apic_sw_enabled().
