MEDIUM: stconn: Forbid applets with more to deliver if EOI was reached

When an applet is woken up, before calling its io_handler, we pretend it has
no more data to deliver. So, after the io_handler execution, it is a bug if
an applet states it has more data to deliver while the end of input is
reached.

So a BUG_ON() is added to be sure it never happens.
