commit 99e675d473eb8cf2deac1376a0f840222fc1adcf upstream.
After commit e3beca48a45b ("irqdomain/treewide: Keep firmware node
unconditionally allocated"). For tear down scenario, fn is only freed
after fail to allocate ir_domain, though it also should be freed in case
dmar_enable_qi returns error.
Besides free fn, irq_domain and ir_msi_domain need to be removed as well
if intel_setup_irq_remapping fails to enable queued invalidation.
Improve the rewinding path by add out_free_ir_domain and out_free_fwnode
lables per Baolu's suggestion.

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.
