MINOR: stream-int: always report received shutdowns

As mentioned in c192b0ab95 ("MEDIUM: connection: remove CO_FL_CONNECTED
and only rely on CO_FL_WAIT_*"), si_cs_recv() currently does not propagate
CS_FL_EOS to CF_READ_NULL if CO_FL_WAIT_L4L6 is set, while this situation
doesn't exist anymore. Let's get rid of this confusing test.
