pci: show id info when pci BDF conflict
During qemu init stage, when there is pci BDF conflicts, qemu print a warning but not showing which device the BDF is occupied by. E.x: "PCI: slot 2 function 0 not available for virtio-scsi-pci, in use by virtio-scsi-pci" To facilitate user knowing the offending device and fixing it, showing the id info in the warning.
