xive: Link "xive" property to XiveEndSource::xrtr pointer
The END source object has both a pointer and a "xive" property pointing to the router object. Confusing bugs could arise if these ever go out of sync. Change the property definition so that it explicitely sets the pointer. The property isn't optional : not being able to set the link is a bug and QEMU should rather abort than exit in this case.
