When handling an error at the point where we try and register all the redistributors, we unregister all the previously registered frames by counting down from the failing index. However, the way the code is written relies on that index being a signed value. Which won't be true once we switch to an xarray-based vcpu set. Since this code is pretty awkward the first place, and that the failure mode is hard to spot, rewrite this loop to iterate over the vcpus upwards rather than downwards.

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.
