This patch fixes getting reset status from the restarted
vhost-user backend in case of reconnection, instead of the
status at the time of the disconnection.

This issue was not spotted earlier because Vhost-user
protocol status feature was disabled in server mode.

Fixes: 47235f16505f ("net/virtio-user: set status on socket reconnect")
Cc: stable@dpdk.org
