[libvirt] [PATCH V2 1/2] qemu: forbid define a capabilities mode hostdev

hostdev has mode "capabilities" for LXC, from formatdomain.html: " Block / character devices from the host can be passed through to the guest using the hostdev element. This is only possible with container based virtualization. since after 1.0.1 for LXC " So forbid capabilities mode hostdev if domain is not LXC.
