filter deviceIdentifiers for subscriptionInfo if callers without perm

Fix a security issue that app can read iccId of sim card(s) without
requiring READ_PRIVILEGED_PHONE_STATE permission when calling hidden
API SubscriptionManager.getAllActiveSubscriptionInfoList. Apply
deviceIdentifier filter to remove those info if the caller does
not have proper permissions. The previous fix forgot to reassign
returned value with filtered result.
