test: Only restore interface with gateway

Browse Source 
When testing with SR-IOV cards, it is time consuming to restored the
full old state and also might lead to ethtool failures.

Hence change the `conftest.py` to only restored the IP address, IP route
and DNS config for interface with IPv4 or IPv6 gateway.
