[libvirt] [PATCH] storage: fix logical volume cloning



Commit 258e06c removed setting of the volume type to
VIR_STORAGE_VOL_BLOCK, which leads to failures in
storageVolumeCreateXMLFrom.

The type (and target.format) of the volume was set to zero. In
virStorageBackendGetBuildVolFromFunction, this gets interpreted as
VIR_STORAGE_FILE_NONE and the qemu-img tool is called with unknown
"none" format.
