The timer values aren't changed after receiving the server's answer. So if the 
DHCPREQUEST to the leasing server (state RENEWING) is not answered, it is 
simply retried (with an exponentially increased retransmission delay between 2 
and 20 seconds) from dhcp_fine_tmr().

However, the lease is still used until the T2 expires. Only then, other servers 
are tried by broadcasting DHCPREQUESTs.
