Revert "Remove redundant SubInfo list identifier access checks"

This reverts commit b6a27a1b.

Reason for revert: While this commit improves the performance for a
single invocation of getSubscriptionInfoListFromCacheHelper for an
app without device identifier access the permission checks within
the synchronized block significantly impact performance for multiple
parallel invocations.
