bhyve: abort and return FEATURE_NOT_SAVEABLE while set feature with a save flag for NVMe controller.
Currently bhyve's NVMe controller cannot save feature values cross
reboot. It should return a FEATURE_NOT_SAVEABLE error when the command
specifies a save flag.

Quote from NVMe specification, page 205:

https://nvmexpress.org/wp-content/uploads/NVM-Express-1_4-2019.06.10-Ratified.pdf

If the Feature Identifier specified in the Set Features command is not
saveable by the controller and the controller receives a Set Features
command with the Save bit set to one, then the command shall be aborted
with a status of Feature Identifier Not Saveable.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.

For information on the CPU architectures and platforms supported by FreeBSD, see the FreeBSD website's Platforms page.
