Xen devel - Jun 2009 - [PATCH] xend: pci: only extract the exact pci BDFs

On some hosts:
[root@localhost ~]# ls /sys/bus/pci/devices/0000:00:05.0/
0000:00:05.0:pcie00  0000:05:00.0          class   driver  local_cpus  resource 
subsystem_vendor
0000:00:05.0:pcie01  broken_parity_status  config  enable  modalias    subsystem
uevent
0000:00:05.0:pcie02  bus                   device  irq     power      
subsystem_device  vendor

Here we should only get 0000:05:00.0, but we also get 0000:00:05.0 unexpectedly.
With the ptach, xend only extracts the exact BDF(s).
