[Libvir] Patch to fix duplicate pause/destroy/shutdown calls

I spent a while chasing an issue where running 'virsh destroy foo' on an HVM domain would result in an error being returned by the HV ioctl. What I eventually discovered is that the code was doing a destroy op via XenD and then also doing it via the hypervisor backend. It didn't typically show as a problem for PV domains because it seems they took longer to destroy - so were still around by the time the HV destroy was was called. I tracked this issue down to the main dispatch methods in src/libvirt.c which would indeed call both the XenD and HV driver backends for pause destroy & shutdown methods. The patch attached simply returns as soon as one of the driver methods returns a success return code.
