available snapshot exists which doesn't have snapshot metadata

[s iwata]

Create snapshot from bootable volume.

Let's say cinder process down suddenly, when snapshot status is changed available.
Restarting cinder process, there is available snapshot that doesn't have snapshot metadata.

When the snapshot doesn't have the snapshot metadata, the status is available is not good.(data and status are mismatched)
