  Fix a bug with non-UDP connections that caused dialogs to not get freed.
  
  This issue crept up because of a reference count issue on non-UDP based dialogs.
  The dialog reference count was increased when transmitting a packet reliably but never
  decreased. This caused the dialog structure to hang around despite being unlinked from
  the dialogs container.
  
  (closes issue #14919)
