s390/vfio_ap: fix handling of error response codes
Some response codes returned from the queue reset function are not being
handled correctly; this patch fixes them:
1. Response code 3, AP queue deconfigured: Deconfiguring an AP adapter
resets all of its queues, so this is handled by indicating the reset
verification completed successfully.
2. For all response codes other than 0 (normal reset completion), 2
(queue reset in progress) and 3 (AP deconfigured), the -EIO error will
be returned from the vfio_ap_mdev_reset_queue() function. In all cases,
all fields of the status word other than the response code will be
set to zero, so it makes no sense to check status bits.
