i915: Fix incorrect depth scaling when enabling/disabling depth buffers.

We were updating our new viewport using the old buffers' _WindowMap.m.
We can do less math and avoid using that deprecated matrix by just
folding the viewport calculation right in to the driver.

Fixes piglit fbo-depthtex.
(cherry picked from commit debf751aeaf0f02b9a7fc0e242ae3b97dde8416f)
