Lockdep correctly complains that one shouldn't call um_free_irq() with free_irq() inside under a spinlock since that will attempt to acquire a mutex. Rearrange the code to keep the list manipulations under the lock while moving the actual freeing outside of it, to avoid this. In particular, this removes the lockdep complaint at shutdown that I was seeing with lockdep enabled.

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.
