Stefano Garzarella f961134a61 vsock/virtio: annotate 'the_virtio_vsock' RCU pointer 
Commit 0deab087b1 ("vsock/virtio: use RCU to avoid use-after-free
on the_virtio_vsock") starts to use RCU to protect 'the_virtio_vsock'
pointer, but we forgot to annotate it.

This patch adds the annotation to fix the following sparse errors:
