vhost: Add VIRTIO_F_ANY_LAYOUT feature for vhost 



In the qemu virtualization environment, when the virtio driver of the
windows image is upgraded to virtio-win 0.1.185, and virtio uses
legacy mode. In the negotiation stage of vhost, qemu's host_features
will enable VIRTIO_F_ANY_LAYOUT, and guest_features will also enable
this feature, because qemu's feature is a superset, so the feature
will be passed to the spdk side through the set feature process,
which leads to "VHOST_CONFIG: Processing VHOST_USER_SET_FEATURES
failed. VHOST_CONFIG: vhost message handling failed.", so we enable
this bit for spdk vhost.
