MINOR: stconn/applet: Handle EOI in the applet .wake callback function

The end of input reported by the endpoint (SE_FL_EOI flag), is now handled
in sc_applet_process(). This function is always called after an applet was
called. So, the applets can now only report EOI on the SE descriptor and
have no reason to update the channel too.
