Maxim Levitsky 7f6a0256d1 KVM: x86: avoid loading a vCPU after .vm_destroy was called 
commit 6fcee03df6 upstream.

This can cause various unexpected issues, since VM is partially
destroyed at that point.

For example when AVIC is enabled, this causes avic_vcpu_load to
access physical id page entry which is already freed by .vm_destroy.

Fixes: 8221c13700 ("svm: Manage vcpu load/unload when enable AVIC")

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.
