88bf803297 Avoid treat normal hosts as unresponsive servers
This is a fix for issue #713

When infra-keep-probing is on, all hosts with expired entries were treated as
unresponsive servers and thus causing problems (see #713).

This commit change that, so that normal hosts with expired entries are treated
as unknown servers.
