pmda: Fix metric identifiers

pmda: Fix metric identifiers

The commit "pmda: Use upstream assigned PCP domain id" updated the
Performance Metrics Namespace (pmns) file, without changing the
corresponding metric identifiers used by the agent.

This change fixes the agent metric identifier values to match the pmns
definitions.
