i965: Fix fast clear of depth buffers.
From section 4.4.7 (Layered Framebuffers) of the GLSL 3.2 spec:
When the Clear or ClearBuffer* commands are used to clear a
layered framebuffer attachment, all layers of the attachment are
cleared.
This patch fixes the fast depth clear path.
Fixes piglit test "spec/!OpenGL 3.2/layered-rendering/clear-depth".
