Matt Roper 91565c85b6 drm/i915: Don't try to look up object for non-existent fb 
crtc->primary->fb may be NULL upon entry to intel_pipe_set_base() if the
primary plane has previously been disabled via the universal plane
interface.  We need to check for NULL before trying to reference
old_fb's obj.

This fixes a regression introduced in
