s390/ap: Unmask SLCF bit in card and queue ap functions sysfs
The SLCF bit ("stateless command filtering") introduced with
CEX8 cards was because of the function mask's default value
suppressed when user space read the ap function for an AP
card or queue. Unmask this bit so that user space applications
like lszcrypt can evaluate and list this feature.
