process all expired nodes rather than those not already marked for deletion (#1103)

This makes sure debug_keep_node is reset and the rest of the reimage processing occurs regardless of reimage_requested and delete_requested being set.

Without this, nodes that are marked `debug_keep_node` do not get reimaged/deleted.
