The vhost connection can be closed
concurrently from 2 places:
* the connection thread itself
* rte_vhost_driver_unregister
The connection thread will terminate
the connection if any recv error
occured. The unregister function
will terminate the connection
together with the thread.
However, there is no sychronization
between those two. The connection
thread runs in the background
without any mutex.
The rte_vhost_driver_unregister
now signals the connection thread
to terminate itself and waits
until it's killed.
