secret: Alter cleanup path for virSecretObjListGetUUIDs

Rather than using "ret = -1" and cleanup processing, alter the return
path on failure to goto error and then just return the data.got.

In the error path, we no longer check for ret < 0, we just can free
anything added to the array and return -1 directly.
