Chris Wilson 0a8ef139df drm/i915: Force the CS stall for invalidate flushes
commit add284a3a2 upstream.

In order to act as a full command barrier by itself, we need to tell the
pipecontrol to actually stall the command streamer while the flush runs.
We require the full command barrier before operations like
MI_SET_CONTEXT, which currently rely on a prior invalidate flush.
