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.
