Sean Christopherson baf6ed1772 KVM: SEV: Set RESET GHCB MSR value during sev_es_init_vmcb()
Set the RESET value for the GHCB "MSR" during sev_es_init_vmcb() instead
of sev_es_vcpu_reset() to allow for dropping sev_es_vcpu_reset() entirely.

Note, the call to sev_init_vmcb() from sev_migrate_from() also kinda sorta
emulates a RESET, but sev_migrate_from() immediately overwrites ghcb_gpa
with the source's current value, so whether or not stuffing the GHCB
version is correct/desirable is moot.

No functional change intended.

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.
