SystemUI: Fix sim pin lock message displaying incorrectly issue

When verify password successfully and no sim card is pin locked,
getSimPinLockSubId returning invalid sub id causes slot name
displays incorrectly.

Do not update sub info if sub id is invalid, remove inappropriate
security message update to avoid displaying incorrectly.
