[dpdk-dev] [RFC 09/24] vhost: pass vhost_transport_ops through vhost_new_device()

This patch propagates struct vhost_user_socket's vhost_transport_ops
into the newly created vhost device.
This patch completes the initial refactoring of socket.c, with the
AF_UNIX-specific code now in trans_af_unix.c and the librte_vhost API
entrypoints in socket.c.
Now it is time to turn towards vhost_user.c and its mixture of
vhost-user protocol processing and socket I/O. The socket I/O will be
moved into trans_af_unix.c so that other transports can be added that
don't use file descriptors.
