net: report completed when context is done in cgoLookupIP and cgoLookupPTR All the Lookup* methods that resolve hostnames eventually call lookupIP or lookupHost method. When the order is selected to be hostLookupCGO then lookupHost calls cgoLookupHost which internally calls cgoLookupIP (the lookupIP directly calls cgoLookupIP). When we provide a context that is cancelled after cgo call, then the cgoLookupIP returns completed == false, which caues the lookupIP/lookupHost to fallback to the go resolver. This fallback is unnecessary because our context is already cancelled. The same thing can happen to LookupAddr.
