Nicolin Chen 5983d1e7d7 iommufd/selftest: Drop parent domain from mock_iommu_domain_nested
There is no use of this parent domain. Delete the dead code.

Note that the s2_parent in struct mock_viommu will be a deadcode too. Yet,
keep it because it will be soon used by HW queue objects, i.e. no point in
adding it back and forth in such a short window. Besides, keeping it could
cover the majority of vIOMMU use cases where a driver-level structure will
be larger in size than the core structure.

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 reStructuredText 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.
