From: BillXiang <xiangwench...@dayudpu.com>
Currently, we have added VHOST_USER_SET_LOG_BASE to
vhost_user_per_device_request in commit 7c211eb078c4
("vhost-user: Skip unnecessary duplicated VHOST_USER_SET_LOG_BASE requests"),
as a result, VHOST_USER_SET_LOG_BASE will be sent only once
when 'vq_index == 0'.
In this patch we add the check of 'vq_index == 0' before
vhost_user_read, such that we do not wait for reply for not
sent VHOST_USER_SET_LOG_BASE.
