ntp: ignore onoffline command for unresolved sources

Browse source 
The onoffline command switches an unresolved source to the offline
status, even when the network is already up.

Ignore the onoffline command for unresolved sources to prevent sources
unexpectedly staying in the offline status, e.g. when the command is
issued from a network dispatcher script (and no other call is expected
later when the name is resolved).
