conf: avoid reporting errors when network driver is disabled

Browse Source 
In previous releases all these methods were a no-op if the network
driver is disabled. These helper methods are called unconditionally for
all types of network interface, so must be no-ops if missing. Other code
will already generate an error if the network driver is disabled and a
NIC with type=network is used.
