[libvirt] [PATCH 2/2] storage: Use virStorageBackendRefreshVolTargetUpdate after wipeVol

[John Ferlan]

https://bugzilla.redhat.com/show_bug.cgi?id=1437797

Rather than using refreshVol which essentially only updates the
allocation, capacity, and permissions for the volume, but not
the format which does get updated in a pool refresh - let's use
the same helper that pool refresh uses in order to update the
volume target.
