X86 cannot store the irq domain pointer in struct device without breaking XEN because the irq domain pointer takes precedence over arch_*_msi_irqs() fallbacks. XENs MSI teardown relies on default_teardown_msi_irqs() which invokes arch_teardown_msi_irq(). default_teardown_msi_irqs() is a trivial iterator over the msi entries associated to a device. Implement this loop in xen_teardown_msi_irqs() to prepare for removal of the fallbacks for X86. This is a preparatory step to wrap XEN MSI alloc/free into a irq domain which in turn allows to store the irq domain pointer in struct device and to use the irq domain functions directly.

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.
