Her name in English is 'Sun Little Dragon', so technically Sunny is a nickname. And he says it with such affection, it becomes one. It's like when a young girl is called Lily or Orihime, and the get the nickname Flower or Princess. They're both either translations of the name or what the name is, but they don' go by it so it becomes a nickname.
