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.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
