Find in eav_attribute an entry with source_model : MageSuite\Frontend\Model\Category\Attribute\Source\CategoryDisplay and delete this entry. Even better, find all source_model entries starting with MageSuite\ and delete these.

This problem is not unique to MageSuite btw. In general it is possible in Magento to define custom attributes which will then be stored in the database. If you uninstall an extension which provided such an attribute, such entries are always left behind.
