Subject: [PATCH 2/2] vhost: don't send RESET_OWNER at stop
Message-Id: <1447399450-29489-2-git-send-email-yuanhan.liu@linux.intel.com>
In-Reply-To: <1447399450-29489-1-git-send-email-yuanhan.liu@linux.intel.com>

First of all, RESET_OWNER message is sent incorrectly, as it's sent
before GET_VRING_BASE. And the reset message would let the later call
get nothing correct.

And, sending SET_VRING_ENABLE at stop, which has already been done,
makes more sense than RESET_OWNER.
