It's possible to get an onBinderDied callback after a call to AIBinder_unlinkToDeath() so we can't delete the objects in callbacks_ until we are done using the void* cookie. Handling the cleanup in onBinderUnlinked will handle the case where we manually unlink it as well as the case where it's unlinked due to death. Test: atest VtsHalHealthTargetTest Bug: 319210610 Change-Id: Iee4783217cc88134af6de0fe66128684ca984dba
