We do not have any cached partitions available on Kubelet start with an
empty container storage in CRI-O. This means that the error log message
is not actually an error and more an information.
This means we now pre-filter those cases and do not `klog.ErrorS` any
more. This helps to avoid log spamming in huge clusters.
