    GlusterFS: Complete snapshot_delete when info doesn't exist

    The snapshot_delete operation will fail if the snapshot info file
    doesn't contain a record for the snapshot, or does not exist.
    This happens in cases such as when snapshot_create fails to commit
    anything to disk.

    The driver should allow the manager to delete the snapshot
    in this case, as there is no action required for the driver
    to delete anything.
