However, the cleanup exercise isn't done before returning.

Additionally added an explicit check that current Characteristic handle is not greater or equal to its value handle. If value handle is equal to Characteristic handle, then second "new_attribute" allocation will overwrite the pointer in service->attributes, which will also cause a leak.
