domain_add_cpu() and domain_remove_cpu() need to kfree() the child arrays that were allocated by domain_setup_ctrlval(). As this memory is moved around, and new arrays are created, adjusting the error handling cleanup code becomes noisier. To simplify this, move all the kfree() calls into a domain_free() helper. This depends on struct rdt_hw_domain being kzalloc()d, allowing it to unconditionally kfree() all the child arrays.

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.
