Remove SelfService Asset Listing Bulk Update and Title Link

The Asset listing in SelfService has a bulk update option that is not
functional.  It also has a link to the title that wants to take the user
to asset search page that does not exist in SelfService.

This patch removes the bulk update option and the title link.
