VMCI: remove unused ioctl definitions

IOCTL_VMCI_SOCKETS_VERSION and IOCTL_VMCI_SOCKETS_GET_AF_VALUE were
never implemented, because VSOCK ended up being implemented as a
generic mechanism with a static AF value.  Likewise,
IOCTL_VMCI_SOCKETS_GET_LOCAL_CID ended up being implemented as
IOCTL_VM_SOCKETS_GET_LOCAL_CID.

This isn't a UAPI header, so it should be fine to remove the unused
values.  I've left a comment noting IOCTL_VM_SOCKETS_GET_LOCAL_CID is
in the VMCI range to avoid unintentional reuse.
