i965: Also emit HIER_DEPTH and STENCIL packets when disabling depth.
From the documentation:
"[DevIVB] 3DSTATE_DEPTH_BUFFER must always be programmed along with the
other Depth/Stencil state commands(i.e. 3DSTATE_CLEAR_PARAMS,
3DSTATE_STENCIL_BUFFER, or 3DSTATE_HIER_DEPTH_BUFFER)."
We normally do this, but BLORP was failing to do so in the case where it
disables depth.
Not observed to fix anything yet.
