With "virtual page-root" review-grid needs restriction to mountpoints
With the addition of the "virtual page-root"-feature (#33852) a person which is not admin now has a root-node to click on to get a full view of changes across all mountpoints (requested in #30630).
But the griddata-functions need to restrict data shown to the mountpoints visible to that person. Check if pid=0 (the real "page-root") is in the list of mountpoints, and if not fetch changes from below all mountpoints visible.

This patch should be applied to TYPO3 4.5 too as the same problem happens even if the virtual root is not there. Indeed, if a backend user choose "Workspace" before he chooses any page in the page tree, he will see all changes in the installation, not only those in his mountpoints. I applied the patch to 4.5.17 and it works well.
