Alyssa Ross 71708c9794 vmm: limit VSOCK CIDs to 32 bits
The VIRTIO specification[1] says:

> The upper 32 bits of the CID are reserved and zeroed.

We should therefore not allow the user to supply a VSOCK CID with
those bits set.  To accomplish this, limit the public API of the
virtio-vsock device to only accept 32-bit CIDs, while still using
64-bit CIDs internally since that's how virtio-vsock works.
