[libvirt] [PATCH v2 7/8] storagePoolRefreshFailCleanup: Clear volumes on failed refresh
If pool refresh failed, then the internal table of volumes is
probably left in inconsistent or incomplete state anyways. Clear
it out then. This has an advantage that we can move the
virStoragePoolObjClearVols() from those very few backends that
do call it.
