vsock/virtio: enable VQs early on probe
[ Upstream commit 88704454ef8b00ea91537ae0d47d9348077e0e72 ] virtio spec requires drivers to set DRIVER_OK before using VQs. This is set automatically after probe returns, but virtio-vsock driver uses VQs in the probe function to fill rx and event VQs with new buffers. Let's fix this, calling virtio_device_ready() before using VQs in the probe function.
