Subject: [PATCH 4.19 008/190] vhost/test: fix build for vhost test

From: Tiwei Bie <tiwei.bie@...el.com>

commit 93d2c4de8d8129b97ee1e1a222aedb0719d2fcd9 upstream.

Since below commit, callers need to specify the iov_limit in
vhost_dev_init() explicitly.

Fixes: b46a0bf78ad7 ("vhost: fix OOB in get_rx_bufs()")
