[PATCH 07/12] virt-aa-helper: Don't probe image metadata for terminated chains

[Peter Krempa]

A terminated chain has a virStorageSource with type ==
VIR_STORAGE_TYPE_NONE at the end. Since virStorageSourceHasBacking
is explicitly returning false in that case we'd probe the chain
needlessly. Just check whether src->backingStore is non-NULL.
