  vhost: correct misleading printing information (2024-04-08 04:11:04 -0400)

----------------------------------------------------------------
virtio: bugfixes

Some small, obvious (in hindsight) bugfixes:

- new ioctl in vhost-vdpa has a wrong # - not too late to fix

- vhost has apparently been lacking an smp_rmb() -
  due to code duplication :( The duplication will be fixed in
  the next merge cycle, this is a minimal fix.

- an error message in vhost talks about guest moving used index -
  which of course never happens, guest only ever moves the
  available index.

- i2c-virtio didn't set the driver owner so it did not get
  refcounted correctly.
