[PATCH 5/6] vhost_user: Don't export several functions

[David Gibson <david@gibson.dropbear.id.au>]

vhost-user added several functions which are exposed in headers, but not
used outside the file where they're defined.  I can't tell if these are
really internal functions, or of they're logically supposed to be exported,
but we don't happen to have anything using them yet.

For the time being, just remove the exports.  We can add them back if we
need to.
