Run the following query:

SELECT
  *
FROM eav_attribute
WHERE (
`attribute_id` LIKE '%stomlayoutupdate%'
OR `entity_type_id` LIKE '%stomlayoutupdate%'
OR `attribute_code` LIKE '%stomlayoutupdate%'
OR `attribute_model` LIKE '%stomlayoutupdate%'
OR `backend_model` LIKE '%stomlayoutupdate%'
OR `backend_type` LIKE '%stomlayoutupdate%'
OR `backend_table` LIKE '%stomlayoutupdate%'
OR `frontend_model` LIKE '%stomlayoutupdate%'
OR `frontend_input` LIKE '%stomlayoutupdate%'
OR `frontend_label` LIKE '%stomlayoutupdate%'
OR `frontend_class` LIKE '%stomlayoutupdate%'
OR `source_model` LIKE '%stomlayoutupdate%'
OR `is_required` LIKE '%stomlayoutupdate%'
OR `is_user_defined` LIKE '%stomlayoutupdate%'
OR `default_value` LIKE '%stomlayoutupdate%'
OR `is_unique` LIKE '%stomlayoutupdate%'
OR `note` LIKE '%stomlayoutupdate%'
);

Remember the attribute_ids from that query and run the following query:

DELETE
  FROM eav_attribute
WHERE attribute_id IN (attribute_ids from first query);

Done!
