Ensure there is no path where we might attempt to save SME state after we flush a task by updating the SVCR register state as well as updating our in memory state. I haven't seen a specific case where this is happening or seen a path where it might happen but for the cost of a single low overhead instruction it seems sensible to close the potential gap.

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.
