virtio/vsock: Fix feature selection

We should advertise to the guest only the features supported by vhost
and kvmtool. Then we should set in vhost only the features acked by the
guest. Move vhost feature query to get_host_features(), and vhost
feature setting to device start (after the guest has acked features).

This fixes vsock because we used to enable all vhost features including
VIRTIO_F_ACCESS_PLATFORM, which forces vhost to use vhost-iotlb and
isn't supported by kvmtool.
