MINOR: stream-int: Be sure to have a mux to do sends and receives
In si_cs_send() and si_cs_recv(), we explicitly test the connection's mux is
defined to proceed. For si_cs_recv(), it is probably a bit overkill. But
opportunistic sends are possible from the moment the server connection is
created. So it is safer to do this test.
This patch may be backported as far as 1.9 if necessary.
