isisd: fix flex-algo affinity setting

The following causes a validation error.

> # cat config
> affinity-map green bit-position 0
> router isis 1
>  flex-algo 129
>   affinity exclude-any green
> # vtysh -f config

> Error type: validation
> Error description: affinity map green isn't found
> The following commands were dynamically grouped into the same transaction and rejected:
> - affinity-map green bit-position 0
> - router isis 1
> -  flex-algo 129
> -   affinity exclude-any green

Data does not exist in memory in validation state.

Get data from the candidate northbound config instead.
