vhost: wrong value return for VHOST_USER_VRING_GET_BASE
When the VM is migrated, the driver sends VHOST_USER_VRING_GET_BASE message to the device to get the vring offset. The device is supposed to shut down the vring, and return the current vring offset. What the code did was to shutdown the vring, initialize the vring, and return 0 to the driver. The fix is to first store last_avail_idx in the message and then close the vring.
