Set the data_in to NULL before using the temporary task.

I'm not sure I understand how this worked so far, because the temporary
stack-based task we use to prepare the successors is barely initialized,
not enough to call parsec_task_snprintf on it. The least info we need to
set is to NULLify the data_in for all task classs flows.
