Encapsulate the handling of the migration_in_progress flag for both VMs in two functions sev_lock_two_vms and sev_unlock_two_vms. It does not matter if KVM_CAP_VM_MOVE_ENC_CONTEXT_FROM locks the destination struct kvm a bit later, and this change 1) keeps the cleanup chain of labels smaller 2) makes it possible for KVM_CAP_VM_COPY_ENC_CONTEXT_FROM to reuse the logic.

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.
