Revert upsteam oslo enforce-scope default changes

Upsteam has changed the default scope oslo_policy enforcement values
to True which has impacted deployments on Epoxy. This change reverts
that change. Note that this fix is valid for Epoxy only and will
not apply from 2025.2 onwards when the option is deprecated.
