s390/vfio-ap: add status attribute to AP queue device's sysfs dir
This patch adds a sysfs 'status' attribute to a queue device when it is
bound to the vfio_ap device driver. The field displays a string indicating
the status of the queue device:
Status String: Indicates:
------------- ---------
"assigned" the queue is assigned to an mdev, but is not in use by a
KVM guest.
"in use" the queue is assigned to an mdev and is in use by a KVM
guest.
"unassigned" the queue is not assigned to an mdev.
The status string will be displayed by the 'lszcrypt' command if the queue
device is bound to the vfio_ap device driver.
