lwip: dns: do not print IP address when a variable is specified
When calling "dns <hostname> <varname>", do not print out the IP address
of <hostname> onto the console. Print it only when no variable is
passed. The reason is to be able to call do_dns() from another command
in need of the DNS services without polluting the output.
