Settings: Show Service State status in Phone Status properly

would be OOS. In such cases, data service state is not checked to
show the phone status UI. Fix to consider data service state also to
update the UI properly.

Telephony: Disable PIN Toggle option if SIM is in Locked state.

When user presses cancel in PIN lock screen, card will be in
LOCKED state and hence cannot access SIM for any transactions.

So Disable PIN Toggle option in Locked State.
