Hmm, I think we need to know what's the current preferred_lft and valid_lft on failed test. Would you please add a debug line so we can get the info after failed?

    slowwait 5 check_addr_not_exist "$devdummy" "10.23.11."
    if [ $? -eq 1 ]; then

•           ip addr show dev "$devdummy"
            check_err 1
            end_test "FAIL: preferred_lft addresses remaining"
            return
  

Given that this is 2nd or 3rd time we're massaging this test case I think we should just add the appropriate debug information to the test itself. Please post a real patch?
