[PATCH] vhost_vdpa: fix unmap process in no-batch mode

From: Cindy Lu
Date: Mon Apr 10 2023 - 11:02:31 EST


While using the no-batch mode, the process will not begin with
VHOST_IOTLB_BATCH_BEGIN, so we need to add the
VHOST_IOTLB_INVALIDATE to get vhost_vdpa_as, the process is the
same as VHOST_IOTLB_UPDATE
