sc-network: Improve invalid boot node reporting (#14455)

This improves the reporting of invalid boot nodes. First, it will only report each boot node once
as invalid and not every time we try to connect to the node. Second, the node will only report for
addresses that we added as startup and not for addresses of the boot node that the node learned from
other nodes.
