While rolling back a snapshot I succeed when I pass in `-K with location of key file, but it looks like I fail when I attempt to use `--secret /path/to/secret` or `--secret=/path/to/secret`.

# rbd --name=client.admin -K ./secret.key --pool lab8_pool_a snap rollback --snap=lab8-001-20120607-001 lab8-001
Rolling back to snapshot: 100% complete...done.

It appears that the map operation is the other way around, where `--secret` does work, while the `-K` does not.

rbd --name=client.admin --pool lab8_pool_a  --snap=lab8-001-20120607-001 -K ./secret.key map lab8-001; echo $?
