[libvirt] [PATCH 1/4] virstorageobj: Don't clear vols if they weren't initialized

[Michal Privoznik]

If virStoragePoolObjNew() fails to create new volume object list
then virObjectUnref() is called and since refcounter is 1 then
virStoragePoolObjDispose() is called which in turn calls
virStoragePoolObjClearVols() which in turn dereferences
obj->volumes.
