[libvirt] [PATCH] conf: Format disk pool part_separator attribute for running pool

[John Ferlan]

Commit id '4f846170' added printing of a new field 'part_separator'; however,
neglected to do so when there was an "freeExtent" defined for the device
(as there would be when the disk pool was started).

This patch adjusts the logic to appropriately format the device path and
if there the part_separator attribute.
