In Pagination if limitstart is set more than the last page via URL or request, the result always giving the last page articles list.
I found this when I try to implement JQuery Infinite Scroll in 'Tagged Items' menu item type. It giving me literally infinite scrolling the page.

Steps to reproduce the issue

1. Clean install Joomla 3.3.6 without additional data.
2. Create a number of articles and give them the same tag.
3. Create a menu item type 'Tagged Items'.
   • On 'Pagination' tab: set Display Select to Hide, Pagination to Show.
   • On 'Item Selection Option' tab: set the Maximum Items so it will give pagination on the front-end.
4. Click on the menu item in the front-end
5. Go to the last page, and via URL change the x in ?start=x (or ?limitstart=x for non sef) to eg. 9999999.

Expected result

Empty list page, or display error that the page doesn't exist, or 404 page.

Actual result

Always return to the last page of that menu item.
