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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
