Allow orerride non roaming according carrier configuration for both

voice roaming or data roaming condition

For LTE environment, a lot of carrier support LTE only condition since
voice go over LTE.
Also some MVNO have domestic roaming with LTE only and that should be
treated as home.
So we need to allow override roaming state even in data roaming
condition.
