[PATCH 1/2] hw/virtio/vhost-user: don't use uninitialized variable

[Changpeng Liu <changpeng.liu@intel.com>]

Variable `vdev` in `struct vhost_dev` will not be ready
until start the device, so let's not use it for the error
output here.

Fixes: 5653493 ("hw/virtio/vhost-user: don't suppress F_CONFIG when supported")
