s390/zcrypt: Fix blocking queue device after unbind/bind.
When the association between a queue device and the driver is released via unbind and later re-associated the queue device was not operational any more. Reason was a wrong administration of the card/queue lists within the ap device driver. This patch introduces revised card/queue list handling within the ap device driver: when an ap device is detected it is initial not added to the card/queue list any more. With driver probe the card device is added to the card list/the queue device is added to the queue list within a card. With driver remove the device is removed from the card/queue list. Additionally there are some situations within the ap device live where the lists need update upon card/queue device release (for example device hot unplug or suspend/resume).
