resolver.ClientConn.ReportError: wrong documentation regarding retries

[fho]

The documentation of resolver.ClientConn.ReportError states:

grpc-go/resolver/resolver.go

Lines 239 to 242 in b850ea5

	// ReportError notifies the ClientConn that the Resolver encountered an
	// error. The ClientConn will notify the load balancer and begin calling
	// ResolveNow on the Resolver with exponential backoff.
	ReportError(error)

But this is not the case anymore since 1c598a1.
The ClientConn does not call ResolveNow() again after an error was reported.
The resolver is responsible for retry resolving after an error and report success by calling UpdateState().
