[libvirt] [PATCH 6/9] storage: Fill in 'type' field for virStorageSource in storage driver

[Peter Krempa]

Storage driver uses virStorageSource only partially to store it's
configuration but fully when parsing backing files of storage volumes.
This patch sets the 'type' field to a value other than
VIR_STORAGE_TYPE_NONE so that further patches can add a terminator
element to backing chains without breaking iteration.
