BUG/MEDIUM: stream_int: Don't check CO_FL_SOCK_RD_SH flag to trigger cs receive

It is mandatory to be sure to process data blocked in the RX buffer of the
conn_stream while the shutr/read0 was already processed. The stream interface
doesn't need to rely on this flags because it already tests CS_FL_EOS.
