If t1 >= t2 timeout then only t2 timer should be scheduled. This can happen when a sub 1 minute lease is received. dhcp_coarse_timer will then trip t2 but leave t1, leaving that triggered on next timer producing "interesting" results.

Attached patch fixes this. It has been running for ten months+ in quite a number of systems and different networks environments.
