When rte_vhost_driver_unregister delete the connection fd,
fdset_try_del will always try and donot release the
vhostuser.mutex if the fd is busy, but the fdset_event_dispatch
will set the fd to busy and call vhost_user_msg_handler to get
vhostuser.mutex, which will cause deadlock. Unlock the
vhost_user.mutexif fdset_try_del fail and relock it when retry.
