Sean Christopherson e2b43fb252 KVM: x86: Apply runtime updates to current CPUID during KVM_SET_CPUID{,2}
When handling KVM_SET_CPUID{,2}, do runtime CPUID updates on the vCPU's
current CPUID (and caps) prior to swapping in the incoming CPUID state so
that KVM doesn't lose pending updates if the incoming CPUID is rejected,
and to prevent a false failure on the equality check.

Note, runtime updates are unconditionally performed on the incoming/new
CPUID (and associated caps), i.e. clearing the dirty flag won't negatively
affect the new CPUID.

Fixes: 93da6af3ae ("KVM: x86: Defer runtime updates of dynamic CPUID bits until CPUID emulation")

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 reStructuredText 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.
