[libvirt] [PATCH 08/14] secret: Change variable names for list traversals

[John Ferlan]

Rather than 'nuuids' it should be 'maxuuids' and rather than 'got'
it should be 'nuuids'.  Alter the logic of the list traversal to
utilize those names.

Also alter the cleanup in virSecretObjListGetUUIDs to return on success
and handle failure with a -1 return instead of the if (ret < 0) logic.
