BUG/MINOR: stream-int: Process read0 even if no data was received in si_cs_recv

The flag CS_FL_EOS can be set while no data was received. So the flas
CS_FL_RCV_MORE is not set. In this case, the read0 was never processed by the
stream interface. To be sure to process it, the test on CS_FL_RCV_MORE has been
moved after the one on CS_FL_EOS.
