drm/i915: clarify gen2 pageflip cmd
I've reviewed gen2 pageflip code to hunt down multiple prepare pageflip
issues. The only thing I've found is a slight but functionally
meaningless confusion about the length of the mi cmd.
Fix it up and add a comment about what this dword should be (according
to docs at least).
