vsock: Increase NUM_QUEUES to 3

Browse Source 
In virtio standard, vsock uses 3 vqs. crosvm expects 3 vqs from
vhost-user-vsock impl, but this vhost-user-vsock device sets up
only 2 vqs because event vq isn't handled. And it causes crash in
crosvm. To avoid crash in crosvm, I increase NUM_QUEUES to 3
