s390/vfio_ap: check TAPQ response code when waiting for queue reset
The vfio_ap_mdev_reset_queue() function does not check the status
response code returned form the PQAP(TAPQ) function when verifying the
queue's status; consequently, there is no way of knowing whether
verification failed because the wait time was exceeded, or because the
PQAP(TAPQ) failed.
This patch adds a function to check the status response code from the
PQAP(TAPQ) instruction and logs an appropriate message if it fails.
