[ Upstream commit 617c66b9f2 ]
When filtering by guest, kvm_stat displays garbage when the guest is
destroyed - see sample output below.
We add code to remove the invalid paths from the providers, so at least
no more garbage is displayed.
Here's a sample output to illustrate:

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
