Subject: [PATCH] vdpa:Fix dirty page bitmap synchronization not done after
 suspend for vdpa devices

Change the flag for vdpa device to determine whether to perform log_sync
from dev->start to dev->log, and do not release dev->log after vdpa device
suspend, and release it uniformly by vhost_dev_stop.
