MINOR: channel/stconn: Replace channel_shutw_now() by sc_schedule_shutdown()

Browse Source 
After the flag renaming, it is now the turn for the channel function to be
renamed and moved in the SC scope. channel_shutw_now() is replaced by
sc_schedule_shutdown(). The request channel is replaced by the front SC and
the response is replace by the back SC.
