[libvirt] [PATCH] rbd: Do not free the secret if it is not set

[Wido den Hollander]

Not all RBD (Ceph) storage pools have cephx authentication turned on,
so "secret" might not be initialized.

It could also be that the secret couldn't be located.

Only call virSecretFree() if "secret" is initialized earlier.
