This reverts commit 6ba88bce64b343761aabe3a6c7ee285c6020a959. The commit
was erroneous because GL already provides a separate guard on the number of
layers you are allowed to render into. On Sandy Bridge, we set this guard
correctly so creating a 3D texture bigger than 512 is fine, you just can't
render into all of the slices at once.
