[PATCH 1/4] qemu: agent: Make fetching of 'can-offline' member from 'guest-query-vcpus' optional

The 'can-offline' member is optional according to agent's schema and in
fact in certain cases it's not returned. Libvirt then spams the logs
if something is polling the bulk guest stats API.

Noticed when going through oVirt logs which appears to call the bulk
stats API repeatedly.

Instead of requiring it we simply reply that the vCPU can't be offlined.
