i965: Delete pre-DRI2.3 viewport hacks.

The __DRI_USE_INVALIDATE extension was added in May 11th, 2010 by commit
4258e3a2e1c327.  At this point, it's unlikely that anyone's using the
right mix of new and old components to hit this path.  Deleting it
removes an untested code path and cleans up the driver a bit.
