VSOCK: Move af_vsock.h and vsock_addr.h to include/net
This is useful for other VSOCK transport implemented outside the net/vmw_vsock/ directory to use these headers. Signed-off-by: Asias He <asias@redhat.com> Acked-by: Andy King <acking@vmware.com> Signed-off-by: David S. Miller <davem@davemloft.net>
