Summary: dialog: missing callback call for timeout on early dialogs

Initial Comment:
This bug is related to bug 1729550 - CANCEL does not update the dialog state:
http://sourceforge.net/tracker/index.php?func=detail&aid=1729550&group_id=139143&atid=743020

The scenario is the same. The dialog will transition from DLG_STATE_EARLY to DLG_STATE_DELETED on a callback from tm (TMCB_TRANS_DELETED) that will generate a DLG_EVENT_TDEL event.

In this particular case, the DLGCB_FAILED is not invoked.


Here's a simple patch that will fix this particular problem.  Maybe this is not the best approach (and it may not cover all other cases, but it is fixing this particular scenario):
