vhost: Clean up how VhostOpts method vhost_backend_init() fails
vhost_user_backend_init() can fail without setting an error. Unclean.
Its caller vhost_dev_init() compensates by substituting a generic
error then. Goes back to commit 28770ff935 "vhost: Distinguish errors
in vhost_backend_init()".
Clean up by moving the generic error from vhost_dev_init() to all the
failure paths that neglect to set an error.
