Restore 3.0 behaviour with empty /etc/hosts

Jeremy, in 3.0 we allowed get_mydnsdomname and get_mydnsfullname to fail
without filling in anything useful. Worked fine. Without this patch and a empty
/etc/hosts and no DNS configured, session setup would return
NT_STATUS_BAD_NETWORK_NAME. This is confusing at best, BAD_NETWORK_NAME afaik
is only ever returned from tcon normally.

This restores the 3.0 behaviour.

Comments?
