From: Erik Karlsson <erik.karls...@iopsys.eu>
Not doing so can result in a use after free since the name for DHCP
derived DNS records is represented as a pointer into the DHCP lease
table. Update will only happen when necessary since lease_update_dns
tests internally on dns_dirty and the force argument is zero.
