The slave removes the slave device when receiving the request with the
stop command.
In the case that the master side guest crashes, the crashed guest, typically,
will be killed by the admin. This event will be captured via the close of the
socket connection, so we can remove the vhost-pci device
When DRIVER_OK, the device sends the mem and vring info to the driver
via the controlq.
