Record the user-provided asynchronous event configuration set via Set Features, and return it in Get Features. This value is not actually used, since AER is not implemented yet in the virtual controller model, but it at least implements the mandatory Set/Get Features. This allows the hack in the NVMe host code that ignored the Set Features failure to be reverted.
