MEDIUM: server: disable protocol validations when the server doesn't resolve
When a server doesn't resolve we don't know the address family so we
can't perform the basic protocol validations. However we know that we'll
ultimately resolve to AF_INET4 or AF_INET6 so the controls are OK. It is
important to proceed like this otherwise it will not be possible to start
with unresolved addresses.
