[ion] 25479: - Fix insertion of special APC into APC delivery list. - Re-identize some APC code (just formatting change). - Detect APC during GateWait. Previous check scanned for DeferredReady, which is incorrect. - Simplfy KeremovequeueApc to take advantage of the fact RemoveEntryList now returns whether the list is empty or not.

Log:
- Fix insertion of special APC into APC delivery list.
- Re-identize some APC code (just formatting change).
- Detect APC during GateWait. Previous check scanned for DeferredReady, which is
incorrect.
- Simplfy KeremovequeueApc to take advantage of the fact RemoveEntryList now returns
whether the list is empty or not.
