return in case expected env vars are not set

In case of IPv6 only setup, IP environment variable should not be
set. Still if we have a routed setup routed_setup_ipv4() gets invoked.

This means that the following command will be invoked:

ip route replace proto static dev tap3 table public

This replaces default route!!

With this patch fixes routed_setup* functions to return early
in case expected environment vars are not set.
