i965: Fix S8 and X8 reversal in brw_depthbuffer_format refactor.

In commit 09d9a8913e8c28fc4c1c60d7da85a2f093786894, I accidentally
botched the X8 and S8 cases.  (I wrote this patch before realizing that
X8 and S8 had been swapped in the big MESA_FORMAT rename, and apparently
didn't rebase it properly after fixing that...)

Fixes regressions in 13 Piglit tests on Ironlake.
