[ Upstream commit 123b7c7c2ba725daf3bfa5ce421d65b92cb5c075 ]
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.
