[libvirt] [PATCH 03/11] conf: Remove dubious code from virDomainPCIAddressSetGrow()

I haven't been able to come up with a single scenario in which the code in question would be executed; even if there was one, it would be due to the user specifying a *partial* PCI topology in the guest XML, which is of course entirely unsupportable and thus providing even the slightest hint that doing so is in any way a good idea is actively harmful.
