ipconfig: fix trivial build error
The commit
5e953778a2aab04929a5e7b69f53dc26e39b079e ("ipconfig: add nameserver
IPs to kernel-parameter ip=") introduces ic_nameservers_predef() that defined
only for BOOTP. However it is used by ip_auto_config_setup() as well. This
patch moves it outside of #ifdef BOOTP.
