abis/close: Deliver S_L_INP_TEI_DN when closing the socket
* HSL/IPA had different socket closing code for the same thing,
create one method for it.
* Both methods tried to send an event but as we are on the close
path the sign_link was already removed from the list and the
input event sending method couldn't find the sign_link using the
sapi/tei provided.
