MINOR: stream-int: Set CO_RFL transient/persistent flags apart in si_cs_rcv()

In si_cs_recv(), some CO_RFL flags are set when the mux's .rcv_buf()
function is called. Some are persitent inside si_cs_recv() scope, some
others must be computed at each call to rcv_buf(). This patch takes care of
distinguishing them.

Among others, CO_RFL_KEEP_RECV is a persistent flag while CO_RFL_BUF_WET is
transient.
