deamon-helper: ensure helper_complete() never returns NULL on success

Browse source 
The in_buffer is initialized with a NULL buffer. If we never receive and
data, the buffer might still be NULL.

Maybe it actually can never happen, but it's not clear that this is
always the case. To be sure, ensure we don't return a NULL buffer on
success.
