storage: Don't allow encryption secretPath to be NULL
Allowing a NULL @secretPath for virStorageBackendCreateQemuImgCmdFromVol would result in a generated command line with a dangling "file=" output. So let's make sure the @secretPath exists before processing. This means we should pass a dummy path from the storage test.
