The functions:
  vringh_abandon_kern()
  vringh_abandon_user()
  vringh_iov_pull_kern() and
  vringh_iov_push_kern()
were all added in 2013 by
commit f87d0fbb5798 ("vringh: host-side implementation of virtio rings.")
but have remained unused.

Remove them.

Hi David,

With this patch (set) applied vlang flags the following.
So I guess that xfer_kern can be removed too.

  .../vringh.c:887:19: warning: unused function 'xfer_kern' [-Wunused-function]
    887 | static inline int xfer_kern(const struct vringh *vrh, void *src,
        |                   ^~~~~~~~~
  .../vringh.c:894:19: warning: unused function 'kern_xfer' [-Wunused-function]
    894 | static inline int kern_xfer(const struct vringh *vrh, void *dst,
        |                   ^~~~~~~~~

Otherwise this looks good to me.
