core: fix possible deadlock on update cluster version
Sort the VMs that are being updated according to the order that
the monitoring updates VM related data to prevent a possible
race when both are done within a transaction (with postgres
lower or equal to 9.2 where updates of entries with foreign
key locks the row of the foreign entity in the transaction
scope).
