parser: Fix entity check in attributes
Don't set the "checked" flag when checking entities in default attribute
values. These entities could reference other entities which weren't
defined yet, so the check isn't reliable.
This fixes a short-lived regression which could lead to a call stack
overflow later in xmlStringGetNodeList.
