dmaengine: idxd: Modify the dependence of attribute pasid_enabled

Kernel PASID and user PASID are separately enabled. User needs to know the
user PASID enabling status to decide how to use IDXD device in user space.
This is done via the attribute /sys/bus/dsa/devices/dsa0/pasid_enabled.
It's unnecessary for user to know the kernel PASID enabling status because
user won't use the kernel PASID. But instead of showing the user PASID
enabling status, the attribute shows the kernel PASID enabling status. Fix
the issue by showing the user PASID enabling status in the attribute.
