The special agent special_redfish queries storage-related endpoints to collect data on volumes and drives.

Some devices return empty id references in the VolumeCollection and DriveCollection. When this occurs, the agent encounters a KeyError: '@odata.id'. As a result, monitoring data from the agent is missing.

This update fixes the issue by ignoring id references that lack an id, preventing the KeyError and ensuring the agent continues to collect data as expected.

Thanks to Andreas Döhler for the contribution.
