[PATCH 06/14] hw/virtio: Use error_setg_file_open() for a better error message

[Markus Armbruster]

The error message changes from

    vhost-vsock: failed to open vhost device: REASON

to

    Could not open '/dev/vhost-vsock': REASON

I think the exact file name is more useful to know than the file's
purpose.
