[IPV4]: ipconfig.c: fix dhcp timeout behaviour
I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set
and dhcp is used.
When a DHCPOFFER is received, ip address is kept until we get DHCPACK.
If no ack is received, ic_dynamic() returns negatively, but leaves the
offered ip address in ic_myaddr.
This makes the main loop in ip_auto_config() break and uses the maybe
incomplete configuration.
Not sure if it's the best way to do, but the following trivial patch
correct this.
