rename helper functions in the acc ramp code to avoid confusion

The word 'enabled' was used in two contexts: Whether ACC ramp is
enabled as a feature, and whether a particular access control class
is permantly allowed/disallowed via VTY configuration.

Rename some helper functions to avoid the use of the word 'enabled'
in the latter context.

This is a port of osmo-bsc commit 0ad90b39b9e638b5e3d926c9261d26e777ca478c
