[pve-devel] [PATCH v2 common] cli-formatter: avoid warning when trying to sort on undefined key

[Christian Ebner]

Example:
    pvesh get /nodes/{node}/qemu/{vmid}/rrddata --timeframe day

If the sorting key is not defined in the dataset, e.g. when a VM was not running
for some time within the given timeframe, this resulted in several ugly warnings.

v2: Oops, v1 is nonsense and breaks sorting.
