s390/vfio-ap: allow deconfigured queue to be passed through to a guest
When a queue is reset, the status response code returned from the reset
operation is stored in the reset_rc field of the vfio_ap_queue structure
representing the queue being reset. This field is later used to decide
whether the queue should be passed through to a guest. If the reset_rc
field is a non-zero value, the queue will be filtered from the list of
queues passed through.
When an adapter is deconfigured, all queues associated with that adapter
are reset. That being the case, it is not necessary to filter those queues;
so, if the status response code returned from a reset operation indicates
the queue is deconfigured, the reset_rc field of the vfio_ap_queue
structure will be set to zero so it will be passed through (i.e., not
filtered).
