Add a fix for the case where the dialout fails. In this case the isp

Browse Source 
interface was left in an active, but not connected, state, which resulted
in data being sent to it and the transmit queue filling up. This happened
because the driver never informed sppp that it shoulkd clean up the
connection. This fix informs sppp that it should clean things up.

The fix was actually developed and tested under -stable, so a short MFC
period seems appropriate, say 2 days.
