Pau Espin 5dbed8160f lchan_fsm: Fix possible NULL ptr dereference in _lchan_on_mode_modify_failure()
_lchan_on_activation_failure(), which calls lchan_on_mode_modify_failure(),
already checks for !for_conn in other paths. Hence, it can be that
for_conn being passed to _lchan_on_mode_modify_failure() may be null.
