[libvirt] [PATCH] Ignore specified target path when creating logical vol

Specifying a target path when creating a storage volume has no effect, since volumes only really use the pool's target path and 'name' field to establish the volume's target. Logical volumes expect a target path to be passed, and it can only cause problems. The attached patch erases the passed target volume and fills it in with the one generated from the create operation. Thanks, Cole
