e1_input: Stop the timer when deleting the signalling link on the TS

Stop the tx_timer when deleting the link on top of that ts. Otherwise
bad things might happen. E.g. when scheduling a write on OML and then
the OML link vanishes...

This is a slight layering violation as there could be more than
one signalling link on the timeslot (at least in theory) so the
queue and the timer should move to the e1inp_sign_link.
