Fix >5 year old PlayerSAO deletion bug

force_delete=true is usually set at shutdown in order to
also remove PlayerSAOs, however when too many objects
per block are detected force_delete is also set to true.
This was intended only for the current loop iteration but
obviously persisted to the next iterations thereby
deleting all other remaining SAOs.
