Subject: [PATCH net-next 0/2] vsock/virtio: add support for device suspend/resume

Vilas reported that virtio-vsock no longer worked properly after
suspend/resume (echo mem >/sys/power/state).
It was impossible to connect to the host and vice versa.

Indeed, the support has never been implemented.

This series implement .freeze and .restore callbacks of struct virtio_driver
to support device suspend/resume.

The first patch factors our the code to initialize and delete VQs.
The second patch uses that code to support device suspend/resume.
