Michael S. Tsirkin db191ba0c8 vsock/virtio: use virtqueue_add_inbuf_cache_clean for events

The event_list array contains 8 small (4-byte) events that share
cachelines with each other. When CONFIG_DMA_API_DEBUG is enabled,
this can trigger warnings about overlapping DMA mappings within
the same cacheline.

The previous patch isolated event_list in its own cache lines
so the warnings are spurious.

Use virtqueue_add_inbuf_cache_clean() to indicate that the CPU does not
write into these fields, suppressing the warnings.
