KVM: x86: fix the error of ioctl KVM_IRQ_LINE if no irq chip
If no irq chip in kernel, ioctl KVM_IRQ_LINE will return -EFAULT. But I see in other place such as KVM_[GET|SET]IRQCHIP, -ENXIO is return. So this patch used -ENXIO instead of -EFAULT. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
