path_id: reintroduce by-path links for virtio block devices
Enumeration of virtio buses is global and hence
non-deterministic. However, we are guaranteed there is never going to be
more than one virtio bus per parent PCI device. While populating
ID_PATH we simply skip virtio part of the syspath and we extend the path
using the sysname of the parent PCI device.
With this patch udev creates following by-path links for virtio-blk
device /dev/vda which contains two partitions.
ls -l /dev/disk/by-path/
total 0
