[pve-devel] [PATCH manager] ceph: services: broadcast versions: improve requesting old version

[Fabian Ebner]

to avoid a "malformed JSON string" warning when there is no old
version present (e.g. after starting a cluster).

get_node_kv will always return something that evaluates to true, so
instead, test if the result has an entry for the current node. Also,
it's enough to request the kv for the current node only.
