Daniel Vetter 5f407751b0 drm/i915: Fixup legacy plane->crtc link for initial fb config 
This is a very similar bug in the load detect code fixed in

commit 9128b040eb

    drm/i915: Fix modeset state confusion in the load detect code

But this time around it was the initial fb code that forgot to update
the plane->crtc pointer. Otherwise it's the exact same bug, with the
exact same restrains (any set_config call/ioctl that doesn't disable
the pipe papers over the bug for free, so fairly hard to hit in normal
testing). So if you want the full explanation just go read that one
over there - it's rather long ...
