[libvirt] [PATCH 4/8] secret: Clean up virSecretObjListAdd processing



Make use of an error: label to handle the failure and need to call
virSecretObjEndAPI for the object to set it to NULL for return.

Also rather than an if/else processing - have the initial "if" which
is just replacing the @newdef into obj->def goto cleanup, thus allowing
the remaining code to be extracted from the else and appear to more inline.
