Before this fix, if rpki_sync_socket_rtr socket returns EAGAIN, then ALL routes in the RIB are revalidated which takes lots of CPU and some unnecessary traffic, e.g. if using BMP servers. With a full feed it would waste 50-80Mbps. Instead we should try to drain an existing pipe (another end), and revalidate only affected prefixes.
