MSIM: Fix subId creation issue when one SIM card state is ERROR

On Multi SIM configured device, if one slot has one valid SIM
card and another slot has a SIM in ERROR state, subId not getting
added as SubscriptionInfoUpdater.java is waiting for ICCID on slot
where card state reported as ERROR.

To resolve this issue, assign IccId to empty string when card state ERROR.
