Fix the wrong CDMA carrier text in expanded status bar

After updating operator, the expanded status bar will update SPN.
For GSM, it will display "no service" if service is out of service.
For CDMA, it always displays SPN which set from RuimRecords.java
 and it displays CDMA carrier.

Check current service state whether out of service, if yes, display
 "no service" instead of SPN.
