When deleting the DNS server, we get the following error message:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
grub> net_del_dns 192.168.122.1
error: ../../grub-core/net/dns.c:646:no DNS reply received.
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
This happens because the implementation is broken, it does a "add"
internally instead of a "delete".
