spapr_drc: Expose 'null' in qom-get when there is no fdt
Now that the QMP output visitor supports an explicit null output, we should utilize it to make it easier to diagnose the difference between a missing fdt ('null') vs. a present-but-empty one ('{}'). (Note that this reverts the behavior of commit ab8bf1d, taking us back to the behavior of commit 6c2f9a1 [which in turn stemmed from a crash fix in 1d10b44]; but that this time, the change is intentional and not an accidental side-effect.)
