qemu: Re-reserve all PCI addresses on libvirtd restart

Browse Source 
When reconnecting to existing VMs, we re-reserved only those PCI
addresses which were explicitly mentioned in domain XML. Since some
addresses are always reserved (e.g., 0:0:0 and 0:0:1), we need to handle
those too.

Also all this should only be done if device flag is supported by qemu.
